Watch at: 00:00 / 00:00:20all right today we're going to be doingan overview of the Suzuki King quad 750the Suzuki King quad 750 was almostidentical up until this last year 20182019 they started to make some changesbefore that they had a couple minorchanges but for the most part the partswere interchangeable service work wasWatch at: 00:20 / 00:40almost identical between the 450s the500 to 700 s and the 750 s the video I'mgoing to show you today is gonna be on a2008 Suzuki King quad 750 I'll show youa couple of differences between the 450to 500 to 700 and 750 my opinion theyWatch at: 00:40 / 01:00slowed it down a little bit when theychanged it to the 750 the 700 justseemed to have a little bit more topspeed possibly bottom and is a littlebit quicker on the 750 but top speed Ifeel like was a lot better on my 700I'll still go pretty quick as fast asyou need to go going down the road andWatch at: 01:00 / 01:20get up and go is is great on thismachine I like this uzuki keen quadsprimarily for the turning radius you canturn very very sharp suspension handleswell we've got aftermarket rims andtires on here they work well just a goodrunning forward I'll show you a couplecommon problems as well hard starting isone of those and I'll go over that herein a little bit first thing I want toWatch at: 01:20 / 01:40ask you guys what your opinion is for anoil change what brands what weights ofoil you like to use so go ahead andleave those in the comments below thisis my lineup here I like the Castrol thesemi synthetic 1040 oil sometimes I useit 2050 but it's just in the winter itgets cold here and so I like to use thatWatch at: 01:40 / 02:001040 especially when it's getting coldersemi-synthetic has some of the additivesthat will prolong your transmission andan engine but not as slippery as some ofthe full synthetic oils is but gearsaver that bail rate oil there I like touse in the front end and then on theback end I just like to use the KawasakiWatch at: 02:00 / 02:20gear wet brake oil and the reason whyyou do thatshow you when we get back to the backend of this four-wheeler but you needthe wet gear brake oil in the backendbecause of the brakes being in enclosedin that rear gear case spark plug is aNGK sometimes I'll use a a CR 6e just aWatch at: 02:20 / 02:40little bit hotter plug I'll tell you whyin the video why we do that kind of goesalong with the hard starting problem andthen for an oil filter there kanan makesit go to an High Flow I've always been afan of for these motorcycles excuse methese keen quads just works well butabout any brain will do on the oilWatch at: 02:40 / 03:00filter going onto the four-wheeler hereI've got a couple of covers that andI've got loose just to make quick ofgetting into it and showing you we'vegot the belt on this side here this willbe your right hand side with a brakepedal on that on that one it's got abrake cable that runs back and I'll showyou the back into here quickgot our brake cable that runs back hereWatch at: 03:00 / 03:20and your rear brakes will be in thishousing here on the other side will showyou adjustment but this is your footbrake here this goes up from your lefthand on the handlebars that's gonna bethat cable there so you want to adjustthose kind of together if your if yourbrakes are wearing which isn't a hugeWatch at: 03:20 / 03:40problem on these keen quads you want tomake sure that you're adjusting thosecables accordingly going back up here toyour foot well you've got just thesethese screws here with a with a rubberplug on the back and these become a bitof a challenge when you are pullingthese off after several years they theyWatch at: 03:40 / 04:00tend to get rusty on this side or orbeat up and scratched filled with dirtand so when you start spinning thesescrews off on these wheel wells here alot of times those rubber dampers willstick and you'll end up just spinningthose rubber dampers at the same timeyou're turning your screw underneathWatch at: 04:00 / 04:20this cover here is your spark plug topull these these plugs off here grab aflat screwdriver stick it in between theactual plug itself and then there's kindof a casing around that plug I'll pullone of these completely out but I guessI've already loosened up just to makethis a little bit quicker but you canWatch at: 04:20 / 04:40see there when you push it together itwidens this area here and will allowthat plug to expand to hold that thesecovers on we've got a lot of those onthis Suzuki on that on the newer SuzukiKing quads about 2014 on they've gotWatch at: 04:40 / 05:00kind of a screw type saying same similarplug but it's a screw type Phillipsscrew works a little bit better butagain when it gets dirt and debris inthere sometimesso there's around those Phillips offwe've got our throttle body here rightright above the cylinder you want tomake sure that there's no debris gettingWatch at: 05:00 / 05:20built up around here and there's someadjustments that you can make they don'tsuggest doing that so I think actuallythese they put a marker on there forwarranty work so that they know thatthese weren't mats where typically ifyou're four wheelers hard starting thisis not going to be the place that you'rehaving issues with so don'tautomatically jump to your throttle bodyand start adjusting screws and stuff ifWatch at: 05:20 / 05:40your four-wheeler ran great before itgot cold or before you change altitudesadjusting the screw isn't going tochange anything the most common problemon these suzuki king quads in the 700sand the 750 s all kind of had this sameproblem was a lot of times that we buildWatch at: 05:40 / 06:00up in your cylinder head so if yourfour-wheeler if it's cold out and yourfour-wheelers having a hard timestarting or it won't start at all whatis going on in and about 95 percent ofthese this this will happen at somepoint is you're getting too much carbonbuildup on your on your valves hereinside your cylinder dome on the headWatch at: 06:00 / 06:20and causing those valves to be held openand so your compression is very very lowon these machines so what you got to dothen is pull that head off of there andwe'll do a video at some point of usdoing that a lot of times at that pointyou'll replace piston and cylinder whileyou're doing itbut the problem is the valves on thisWatch at: 06:20 / 06:40machine there's just too much buildupand the reason why I say we we switchedto ang k CR 6e is if the burns a little bithotter the best running four-wheelersfor the most amount of miles I've seenour guys that are using thesefour-wheelers about a hundred percentWatch at: 06:40 / 07:00throttle all the time obviously that'san exaggeration but the guys that arereally using these four-wheelers thoserun the best at fifteen to twentythousand miles a lot of times a lotbetter than the people that are putting100 miles on a year so I would suggestswitching to a hotter plug that wayyou're burning up all the fuel that's inyour cylinder there and then just youWatch at: 07:00 / 07:20know taking out down the road going wideopen just just really using this forwardhard that's what it's meant for and itruns the best when you're using it veryvery hard behind here's your spark plugand a lot of times getting it gettingthrough there above the front rightwheel is going to be easier but that isWatch at: 07:20 / 07:40that is your spark plug wires they're alittle bit of a trick getting that sparkplug off a little bit of a challengeeven seeing it if you can see it rightback up in there this is your frontright shock here but what I like to dois grab a small 3/8 extension and thenit takes it takes a 5/8 socket and youWatch at: 07:40 / 08:00say well this is a metric four-wheeleryes but the 5/8 socket works well it's athin wall I use a 12-point it's a thinwall socket so it slides din down inthere well if you use a longer extensionthan this you're gonna hit your steeringstem you're not gonna be able to getthat socket down in there so I'vetouched these two on there then what IWatch at: 08:00 / 08:20do I loosen it up with a socket and thenwhat I do is put my swivel on there justkind of gives me a little a better gripand then I start turning that spark plugout at that point then what I what youhave to do then is grab a magnet andstick it down in there and pull thatspark plug out and then you can you canWatch at: 08:20 / 08:40replace it just by carefully droppingthe new spark plug down in that holethere same process these two combinationof these two and nothing longer for anextension you can drop these down inthere andtighten it up there are a lot of threadson that sparkplug so you feel likeyou're not doing anything for quite awhile you are tightening that up takes aWatch at: 08:40 / 09:00while to get snug front differential ishere your fill plug and your check plugis here so this takes a 10 millimetershex - for your fill plug here a 10millimeter bolt there is your check boltand then underneath there we didn't pullthe skid plate off for this video butWatch at: 09:00 / 09:20underneath here is a 21 millimeter boltso go ahead and pull there's four tenmillimeter screws here you can see fourof these ten millimeter bolts will pullthis plastic skid plate off then you'llbe able to get to your 21 millimeterplug drain your plug or drain your oilthere this is gonna be a thick oil so IWatch at: 09:20 / 09:40suggest pulling these two caps will helpit drain a little bit quicker when youroil is drained put that bottom plug backin and then use a either a hose or aspecial special funnel to fill this oilwhen that oil starts to come out yourfeel the fill bolt hole there you canWatch at: 09:40 / 10:00put your fill bullet hole in and that'sagain that's a 10 millimeter and then goahead and put your plug on that's whereyour need to be for full so radiatorhere we've got a reservoir here aseparate overflow reservoir here justmake sure your coolant is between theselines and just kind of uses it's anWatch at: 10:00 / 10:20overflow if your radiator gets hotbuilds up pressure it'll spit somecoolant into here if your radiator getslow it'll suck some coolant out of hereso in front headlights they're up tophere is a little cover you can pull onthat there and underneath there is goingto be your radiator cap make sure yourWatch at: 10:20 / 10:40coolant is topped off we've got a Suzukibumper here I like this bumper it workswith no excuse me we've got a moosebumper here works well looks sharp theonly thing I don't like is when you haveyour winch on here it'll wear this likecrazy and at some pointthat'll be worn completely through soWatch at: 10:40 / 11:00either have to get some sort of a mountthat will pullthis roller system out or we're gonnaend up having issues here I've seen someguys just cut it here you are braced oneither side of this so you couldpotentially do that but if you're reallyutilizing this bumper to its fullpotential you don't want to cut anywhereon this bumper to minimize the strengthWatch at: 11:00 / 11:20their front wheels are going to be adisc brake system and we've got a CVshaft here and boots you want to inspectregularly if they've got any sort of ripor a tear at all and I'll show you aseparate video on replacing those but ifyou have any sort of aware at allWatch at: 11:20 / 11:40ripping those boots if you don't getthose replaced immediately you'll end upreplacing that drive shaft so let meknow if you need those drive shafts I dosell those new and used so be carefulwhich ones you get there's a lot ofcompanies out there that'll sell itcheap CV shaft what you don't want torisk is these splines in here on thisshaft if you go with a cheap drive shaftWatch at: 11:40 / 12:00a lot of times these will wear you'vegot an expensive housing here this frontdifferential and if these gears are nottight they're not built with qualitythen you're going to destroy your frontdifferential gear inside here so saving$50 or $100 on the CV shaft man upWatch at: 12:00 / 12:20costing you $1,200 on a frontdifferential so keep that in mind we'vegot adjustable shocks here got a spannerwrench that I'm a lot of dealersdealerships will carry but you can alsojust use channel locks very carefully Ilike to take the weight off this frontwheel here you can see it's in theWatch at: 12:20 / 12:40tightest setting here and that's ifwe've got a sprayer on front if you weuse a winch and a snow blade like we doyou'd like to tighten these up to get asmuch suspension up front as you can orthe stiffest suspension that you canthis is not a power steering model thisis a 2008 before they came out withpower steering on the king quad 750 soWatch at: 12:40 / 13:00you can see inside here would look alittle bit differently on this steeringstand watch a shorter steering stemI just looks a little bit different soVIN number on these models are gonna beleft hand wheel here right above thatright on the frame it's engravedso iflooking for the VIN number if you'relooking for the year check the tenthWatch at: 13:00 / 13:20digit so count ten digitsthis one is else kyun is 2009 so tenthdigit is a nine on this model on thismachine here so that's a 2009 so winchbalance up down here we've got a brokenbolt so that's gonna get replaced herewhile we're servicing it make sure yourreaders radiator is completely cleanedWatch at: 13:20 / 13:40out I like to test these fans you can dothat a couple different ways check myvideos on that we'll do a demonstrationof testing these fans or if you're outriding you're learning it overheatsfirst thing I would do is check that fancheck that radiator make sure it'scleaned out make sure it's in goodcondition so replacing the bulbs onWatch at: 13:40 / 14:00these machines you've got a rubber caphere just go ahead pull that rubber capand underneath there is your bulbthere's another rubber cap here go aheadand pull that off and you can replaceyour bulb very easily on there so againlet me know if you need those bulbs wedo have those available as well so frontWatch at: 14:00 / 14:20rack on this model unfortunately it'snot extremely strong the reason why it'snot is you've got a front rack that'sclear up here and then you've got bracesthat run all the way down here kind of athin-walled brace here I've seen worsethese are a little bit thicker walledthan a lot of the Yamaha Grizzliesthey're extremely thin walled you putWatch at: 14:20 / 14:40any kind of weight up here and thatstarts shifting around what's gonnahappen is that's gonna that's gonna movepivot these back and forth and sidewaysif you're hitting bumps and such andthat is going to make these smaller endsthere it's gonna wear out a lot quickerso from actuator for the four-wheeldrive and the differential lock theWatch at: 14:40 / 15:00front diff lock is here and inspect thatI've had where these seals in behindhere start leaking and you'll run yourdifferential low on oil so make sure youverify that those are in good conditionno leaks there tie rods one on eitherside I could have showed you that on theWatch at: 15:00 / 15:20other side but we've got a lock nut onthis side then we've gotlocknut down here and if you need toadjust your tie rod you have to loosenbulldoze lock nuts they're so moving tothe left hand side here we've got ouryeah recoil pull starter here and thatwill be by your left shin and the newerWatch at: 15:20 / 15:40machines believe the 450s or the 500excuse me they stopped putting a recoilpull starter on there I feel like that'snot a good upgrade because it is nice ifyou're out and your batteries drainedwhich I have seen many times on thesemachines regulator rectifier goes badWatch at: 15:40 / 16:00battery's not charging like it should orholding the charge you will want arecoil pull starter so my opinion thisis a good thing to have on your machinepull this cover here again there's threeclips to pull this cover off and this isyour oil dipstick here and drain yourWatch at: 16:00 / 16:19oil we've got a snow play snow plowmount on this one we've got a hole throwfor the for the drain plug here and it'sa 17 millimeter and it's just right kindof in the center there's gonna be alittle hard to see but drain your oilthere and then your fill is here itWatch at: 16:19 / 16:40takes 2.3 or 20 300 milliliters andthat's about 2.3 quarts now I've foundand here's another question for you guysI'd like you to comment and let me knowwhat you guys have thoughts are but Ifound if you put 2.3 in there yourfour-wheeler is going to be low on oilWatch at: 16:40 / 17:00so next question for you do you putthree quarts in where it needs to be ordo you put 2.3 what do you guys do letme know that in the comments below nextquestion for you do you screw thatdipstick in or do you just dip it inlike what makes sense it's a dipsticknot a screw step stick so let me knowyour thoughts on that if I have anyWatch at: 17:00 / 17:20experts out there or think you'reexperts let me know what thoseyour opinions are gearshifter it comesdown here so we've got a linkage heresometimes you'll find that you need topull this cover off and adjust thisshaft here so that is where you wouldWatch at: 17:20 / 17:40just like a tie rod thereit's a linkage that you would loosenthis 10 millimeter lock nut here thesame thing on the other side of thisgear shifter and you can adjust thatit's going to turn both of ends here toadjust where your knee where needed sowe've got our high nor low or we've gotour gear shifter here we've got a highWatch at: 17:40 / 18:00low neutral and reverse and if you'repulling any sort of a load at allobviously have that in a low position ifyou don't you will destroy belts andclutches fairly quickly so just a just anote there if you're pulling anything atall put it in low gear so going on - ohI forgot oil filter is gonna be on theWatch at: 18:00 / 18:20front of your engine right right infront of or I guess yeah right rightbehind this front rear of front lefttire I like to pull this clip down hereand then I take and I'll actually Bendthis up set it on the tire but your oilfilter is there clear back in there youWatch at: 18:20 / 18:40can see that and I don't like that oildraining on my skid plate so what I dois I'll put a little pan in underneathof that oil filter let that oil from theoil filter drain directly on that oilpan that's there instead of on the skidplate because then you're gonna have adrip of oil for quite a while afterwardsWatch at: 18:40 / 19:00regulator rectifier is here I'vementioned that that is a little bit of acommon problems on these machines we'vegot our stator underneath here thatstator produces powered goes to yourregular directive fire if you are ifyour stator is having issues yourregular rectifiers having issues yourbattery's not going to get the powerWatch at: 19:00 / 19:20that it needs to maintain where it'salready at sometimes even charge alittle bit so regular rectifier is acommon problem you want to make surethat your battery is charging over 14volts if you give your four-wheeler somethrottle smart p.m. that regularrectifiers should be allowing enoughpower to bounce your battery upWatch at: 19:20 / 19:40past 14 volts so double-check that makesure that that regulator rectifier isworking that's the cheapest and easiestplace to start there is that a regulatorrectifier there's just a couple statsfor you tire pressure on the tires therewe've got front is going to be 5.1 PSIrear gin before point four and the tireWatch at: 19:40 / 20:00size is there again we have aftermarketrims and tires so we've got a little bitbigger tires on here those that would bestock though what they have there we'vegot a storage box in the back here thisis not a seal storage box so keep thatin mind I like to it just a rubber strapholding on pop that off there I like tokeep my trailer ball there and aWatch at: 20:00 / 20:20crescent wrench to put that ball onthere and just go ahead and put thatback in there that way if I'm needing topull a trailer or drag or anything I canjust throw that ball on CV Shabs in theback just like the front there you cansee there that we've got a rip and thatis something that we just caught theother day so I'll be doing a separateWatch at: 20:20 / 20:40video on how to replace that that bootthere on that drive shaft just justrippedI know exactly when it happened afterthinking about it so I know that thereis no more than a mile on this driveshaft after I ripped that boot there sowe'll need to replace that the shockssame as the front you can adjust theseWatch at: 20:40 / 21:00with a spanner wrench or with a crescentwrench these we don't have as tight justa little bit smoother ride and becauseof not having a snow blade on the rearwe can have these a little bit looserwheel bearings are in here and so if youneed to pull these if you if you've gota squeak or a tick or these wheelWatch at: 21:00 / 21:20bearings or are just completely shot alot of wobble in your in your hub therego ahead and pull your hub or put yourwheels there it's a 17 millimeters forthe lug nuts there then go ahead andpull this axle nut pull these two topand bottom bolts there and pull this huboff replace those wheel bearings and wecan do a separate video on that at thatWatch at: 21:20 / 21:40time IRS on this dance for independentrearpension and taillight is here on thismachine same thing as the front we'vegot a little bit of a an angle here soif you're putting an incredible a largeamount of weight which you shouldn'thave wouldn't suggest doing on these youcould potentially bend these arms youcan see they're a lot thicker steel thanWatch at: 21:40 / 22:00the front and can support quite a bitmore but but still not as strong as somepeople think they should which is whythey put a weight limit on how muchthose are supposed to hold their exhaustpipe on the right-hand side of the rearthere is our wheels there with our lugnuts again 17 millimeters those are aWatch at: 22:00 / 22:20acorn nuts so they are tapered or seeinga tapered lug nut so they will just keepthat in mind changing on the wet gearbrake oil on this rear differential herewe've got your fill bolt here and thenunderneath the differential again Ibelieve for possibly six of these tenWatch at: 22:20 / 22:40millimeter bolts need to be removed toremove that skid plate and you've got a19 millimeter nut on the bottom of thisdifferential and so it would be the only19 no meter on this differential so ifyou're wondering if you got the rightdrain plug it's it's a 19 millimeter soand then go ahead fill this you actuallyWatch at: 22:40 / 23:00fill this to the top of this fill markhere or it's you need to the top of thisfill you fill this rear differential toyour fill plug here so if I pull thisoff you will see oil sitting directlyWatch at: 23:00 / 23:20underneath of this plug and there you gothereVoyles all the way up you see there ifthat oil plug was clear up here on thetop that's obviously not how you'regonna fill it on the front differentialthe oil the oil fill mark plug is alittle bit farther up here that's whyyou've got a oil check Boulder an oilWatch at: 23:20 / 23:40fill mark down below there so if youfill it up to here not half yourdifferential is full allows the room forexpanding when it gets hot it also keepseverything lubricated so another booththere with the joint on the backside ofthatthey're just verify that that is no ripsin there no issues there I did tell youWatch at: 23:40 / 24:00I was going to show you how to adjustthose brakeswe've got wing nuts here on your brakesyou don't want the pressure on theseconstantly so make sure that you've gotroom for these to move back and forthand that way that way your brakes aren'tconstantly being engaged so going up toWatch at: 24:00 / 24:20the handlebars here just want to showyou a couple things we've got our winchwhich a lot of times this is how it'sgonna be winch on this side here we'vegot your start button here your overridesome people are gonna wonder what thatisthat is reverse kind of a limiter inReverse so if you are wanting to go 65Watch at: 24:20 / 24:40miles an hour and reverse you're gonnahave to hold on that plug there that'sgonna allow you to go that fast so ifyou're just wanting to go I believe it'sfour or five maybe eight miles an hourin Reverse you don't need to hit thatoverride a lot of times when I'm backingup yeah I will just sit there right onthat limiter your lights your lights onWatch at: 24:40 / 25:00this model they'll come on you can turnyour four-wheeler on the first one herewe've got your lower lights on yourfirst click there and we've got your toplights on your second click the 450saren't gonna have this top headlightWatch at: 25:00 / 25:20here so just keep that in mind you won'thave the three settings there you wantyeah you won't have the on lights andlights the 750 just have this extralight up top here so now you got youron/off switch here that simply kills thespark and you're a four wheeler youWatch at: 25:20 / 25:40actually your fuel system here you canhit your Start button there won't starta lot of times guys will bring boilersinto the shop wondering why in the worldisn't my start working my starterworking here we flip that on and you'llstart just fine so we've got your highand low beam there on your left-handWatch at: 25:40 / 26:00side going over to your right hand sidewe've got your four wheel drive if youpush your full all drive button therefor welldrive light will come on yourdifferential lock is not all four wheelsaren't actually engaged until you slidethat differential lock up and that'sgonna be the symbol that it shows thereyou can have a light there so you don'tWatch at: 26:00 / 26:20want to drive fast in that differentiallock nor do you want to turn sharp orspin your wheels really fast so keepthat in mind shut that offrarely do I have that differential lockon its a I get in a really stickysituation I'll throw that differentiallock on hydraulic front brakes therecheck your level they're not not a hugeWatch at: 26:20 / 26:40problem on these we've got two Phillipsscrews up top here and it's a dot forfluid that you're gonna use in this fourwheeler underneath the seat here I'mgonna pull this off quick there's alatch in the back there you can't seebecause of my my back seat that I put onWatch at: 26:40 / 27:00there but fuel tank is gonna be on theleft-hand side kind of to the rear ofthe seat we've got your CDI box thereuses are underneath here a lot of timesthey'll put the the winch solenoid inthe back here sometimes they'll put itin that back storage box that's yourstarter solenoid here we've got a testWatch at: 27:00 / 27:20plug here and I can show you in aseparate video I'll show you someDiagnostics it's a Diagnostics plug forthis model that is here getting start arelay I came here if I said that or notyou got thirty thirty amp fuse on thisWatch at: 27:20 / 27:40starter relay found right underneath ofthis plastic cap here and that fuse ifthere's an issue with the battery toomuch power or something it'll blow thatfuse also causing it not to start youcan see there we have an incredibleamount of buildup on this battery thesame way with on this side I've actuallyWatch at: 27:40 / 28:00unplugged my winch because I wasthinking baby maybe that was what wascausing the build up but I think we'vegot other issues and I'm going to diginto that this isthis is causing us to have some hardstarting issues it just up just abattery drain and causing issues sowe've got to do some cleanup on thatWatch at: 28:00 / 28:20corrosion there possibly replace thatbattery air filters underneath hereyou've got two of these plugs here itkind of sits right oh it does sit rightin between your legs underneath this isa butterfly screw to pull that oil orthat excuse me that air filter there sodry storage is gonna be by your rightknee on that side just a about 1/8 turnWatch at: 28:20 / 28:40and it's got a rubber seal to keep thatdry storage dry just to kind of a smallcontainer there for cell phone and stufflike that but you want to make sure thatthat lid is on there properly beforeyou're going through any sort of thewater so that is the king quad 750 againWatch at: 28:40 / 29:00if you have questions or want me to doother videos on this machine make sureyou let me know those in the commentsbelow please answer some of thequestions that I've asked I'd like toget you guys's opinions and what yourguys's thoughts are if you've got if youfound this video helpful please likesubscribe and share thanks for
