4WD Mini Rock Bouncer Build Suzuki SV 650 Part 2

[@jonathanhudson4623]

I've seen mini rock buggies use the engine and transmission from front wheel drive cars. Everything from the little v-tec 4 bangers up to Pontiac grand prix GTPs with the factory Eaton supercharged 3.8Ls. Some where auto and some where manuals but they would sitt the engine and transmission in the custom 4x4 chassis so that one sides CV axle would act as a drive shaft for the front differential and the other sides CV axle would run to the rear axle. They would reuse any parts they could like the disc brakes and other parts. Not to mention if they picked the right engine and transmission combo they would have alot of aftermarket performance options to choose from. They made for some very interesting and rather potent buggies. Light weight mini buggy with a strong FWD car's drive train made for very few pounds per horse power to move. The power the weight ratio was everything for those mini buggies. Basically the same weight as a side by side when it came to the chassis but youd have the HP and low end TQ of a cars engine. The GTP supercharged 3.8L wasn't a slouch in a 3600+lb sedan. Just think of what it would do in a 2000lb or so 4x4 mini buggy chassis.

[@MullinPerformance]

Chris push everything over to the passenger side! Sit side saddle of the motor and clutch. That way you have all the room for your body and it puts the center of gravity a lot power.

[@wadewright3556]

Then what do you do with the drive shafts? They can't be off centered.

[@MrBenstero]

@@wadewright3556 yes they can. He can move the differentials to one side of the axle and have different size axleshaffs. This is the only way he'll be able to keep a low center of gravity.

[@chrisbrookshire861]

@@MrBenstero Yeah and maybe use some cv joints for any off angles. But u joints can handle some misalignment.

[@MullinPerformance]

@Montana West Photography Studio This is exactly what I was thinking too. That's a bad ass bouncer. Chris can move all that junk too one side and use his body as counter weight. That's the only way too keep this from looking so goofy.

[@rswany16]

I actually had an idea to do that to a 4 wheeler a long time ago. Stretch the chassis and move the engine and trans to one side. I should really try it someday!

[@joecolosi1795]

I’ve known Chris since before he was a you-tuber… he has a great mechanical mindset… being able to see what he wants and then being able to build it… a good man to boot. Hey Chris … tell your dad to be careful when he’s out climbing.

[@joecolosi1795]

@johnnytheprick he’s a great young man… he loves and honors his family. I know I’ve given him a couple go-cart frames and a motor or two … not sure about the rest of the community… I do know that he’s got a crab of a neighbor who lives just down the street that he has to deal with occasionally… someone who acts just like Jeff Dunhams “Walter” but otherwise he’s got a good bit of support I would say. I need to go see him, I have run across a bunch of taps and dies that I bet he could use and I would rather he benefit from them than some stranger when I croak off..

[@joecolosi1795]

@johnnytheprick He lives in a mountain town called Weaverville, which is a lot like what you see on the Andy Griffith show, 11 red lights in total in the whole town … it’s a beautiful mountain town, where the weather is not too hot nor is it too cold. We only had what, maybe 2 really cold weeks this year and it never got below 9*F I don’t think and the summers are quite nice with an average summer temp of about 85*. I will be sure to tell him hello. May swing by his house after I get out of my dentists appointment later today…

[@ronloesch8718]

You will need to add slip joints to the drive shafts they were intended for the differentials to be fixed, now your differentials will be moving up and down causing the length of the drive shafts to vary.

I imagine scraping the cvt would be the best, fair enough it would be easier and more user friendly with it, but cvt's drain A LOT of the power from the engine. Also with a 650 v-twin the factory clutch and engine should make it fairly easy to get going, and with a low series as well it should be no issue. I think the cvt will cause more headaches than pleasantries

[@clarkb1900]

I agree. Plus you can't have the CVT slip for control (like with a hydraulic) without burning the belt.

[@All_SportGG]

Yeah i agree

[@evanwebber9981]

The diffs probably have some amount of gear reduction, so it should be fine with just the SV650 factory setup. I've thought of doing something like this for years.

[@clarkb1900]

@@evanwebber9981 Exactly- between the diffs, the 2 speed box, and the engine's tranny the gearing'll probably be pretty low. And with a chain going between the engine and T-case, the gearing could be finetuned with different sized sprockets.

[@musicauthority7828]

I don't think the CVT system belongs, but you are wrong about it robbing power and torque. one has to look no farther than snowmobiles to see that.

[@colinvannamee3994]

here is a thought for you, you can offset the engine and transmission to the right like a lot of full sized special built rock bouncers. making room for you to sit next to the engine transmission, lowering your overall height and center of gravity and giving more room for suspension travel.

[@lelisatachaguacabrera1408]

Jalgd usar

[@jgallan7733]

hey there... you have to dump the cvt....it works off rpm...at the crank....when you use most of the gears in the tranny you will not have enough rpm...do the math on the gear ratios....just stick with the motorcycle trans chain drive to the wheeler trans, and the low range in the wheeler trans will will multiply your gear reduction...much simpler setup .....i do not believe the cvt will work like you think...great job... you are one dedicated young man

CVT engagement when being driven off of the gearbox may only work properly in a couple of the gears… depending on what RPM it’s setup to engage/disengage.

[@brianpiper3188]

I agree! The 2016 Polaris Sportsman 570 I used to own idled at 1200 rpm, engaged the CVT at about 1300-1400 rpm. For reference, 44 hp engine.

[@mdnovaman]

It’ll only work properly from 4th upward on the engine (1:1 gear ratio). Any other gears it’ll need the engine to be revved really high first. Best off just throwing all the cvt in the bin.

[@brianpiper3188]

@@mdnovaman I'm ok with CVTs, but I think that would be the best.

[@fitzfarm8694]

It will just depend on how he gears it going from the motorcycle transmission to the cvt. With the proper sprocket size he will be able to used all 6 gears.

[@lizzard7473]

@@fitzfarm8694 i think you may be the only one who has properly thought this out. Its really going to be tricky. I think that once he gears it high enough to engage in the lower gears it will effectively cancel out the usefulness of the lower gears. Leaving just the high/low range in the gear box as the effective difference. Its I think over complicated. But this guy is all about exploration and is bright enough to find a solution.

[@therockbiter8140]

Had an 07 Sv650s, I put 140k miles on it without anything more than regular wear items, oil, filter, chain, sprockets, pads and tires. It was a flawless bike after upgrading the suspension to some TLR forks and a 636 rear shock. I think it had tighter gearing than the XR650l I traded it in for, if you just gear it down and add a F-W-R box it'll be fine for crawling. It's got plenty of grunt.

Pro tip for you here, On Polaris McPherson struts the lower ball joint can be easily removed by using a grease gun you remove the three screws that hold the plate that holds the ball joint on and then you pump grease into the grease fitting and the hydraulic pressure pushes the ball joint right out!!!

[@MrBenstero]

11'' of ground clearance under the axle is very good for a solid axle. You can offset the whole drivetrain to one side to lower the center of gravity. Using extensible driveshafts you don't have to have a straight line to the diffs, they can be offset a little and it won't hurt your angles too much. But if you don't want a grave digger 454 type of rig you have to offset you and your drivetrain. Good work so far

[@Najsed]

As many people are saying, the cvt will probably be useless, especially on a rock crawler. A lot of people use fwd car gearboxes as transfer cases in thise kinds of builds. Just weld the diff and cut the bellhousing off. That way you get some extra gears, reverse and extra gear reduction (final drive). You could end up with a ridiculous crawl ratio! Really excited about the build btw.

[@DktheWelder]

I reckon the seat with legs over the transfer box would be best . I don’t like using the cvt after the motors gearbox when in high gears it will spin too fast to labouring the motor and clutch, I think a sprocket on that transfer box is better but you will make it work either way👍

Rear steer idea... Link bar steering in combination with a boat steering cable setup for both front and rear

[@soberbrent]

Unless you overdrive the cvt pulley only the last or second to last gears of the motorcycle trans will spin the cvt fast enough to engage. Also the cvt for a rzr will probably have some ungodly high engagement like 4K or more rpm. Scrap the cvt or it will just be another parasitic loss in the drivetrain. If it’s a fear of stalling. Look into getting a rekluse clutch for the engine. Grind hard plumbing use those in almost all of their builds.

[@gregholloway2656]

Agreed. The primary cvt clutch needs to spin at engine speed, or it won’t engage properly. Could just leave the bike trans in 1:1 with no shifter.

I am so excited for this build. I have been asking for it for a 4x4 build for so long now!

[@bjfishing9046]

So IF you intend to use the Polaris Hillard clutches in the front hubs then you actually can have 2wd/4wd select. Long story short each hub needs a 12v positive going to an armature plate that acts like an electro magnet in the back of the hubs. This engages the 4wd. Turn the 12v off and it disengages 4wd. This system in your case should be treated like any older 4x4 and you'll need to come to a compete stop everytime you engage or disengage. Also advise reading up on the systems and servicing them. Pretty decent systems just different from what most ATVs use. Polaris actually still uses the system in a different form to this day.

[@MactastiK83]

There are slip joints on the Polaris gearbox itself that are even greaseable. If you added another slip joint into the shaft it would force the ujoint into the gearbox output shaft and destroy the ujoint or the gearbox output shaft. The slip joint is built into the ujoint knuckle that slips onto the shaft.

[@williamnail7672]

Outstanding mission and idea!
