Homemade 4 wheeler problem! Clutch problem or Engine?

Recommended Posts

I have this 4 wheeler that I am building and i have encountered a problem.

The 4 wheeler will not move!

I am a beginner to all of this.

The clutch over inside is rotating but the chain is not moving; I already replaced the clutch it is brand new.

The clutch overheats and it starts to shoot out smoke.

Is this a clutch problem? Am I using the wrong type of clutch?

The clutch is a Max-Torque 3/4 in. bore and 10 teeth.

Or is the Engine too small? Is the 4 wheeler to heavy?

Im using a Briggs and Stratton 3 hp 127 cc 3600 rpm

Here are some pictures of the clutch and the engine.

That seems like a cool project. I would have to take a close look at the details to comment on the clutching.

There is really nothing to see in detail. The clutch does not lock on to the chain to make the wheels move. The inside of the clutch is rotating and its not moving the chain.

So do you even have a sprocket on the clutch side?

Doe's it roll freely if you push it around? Jack the back wheels off the ground & make sure the rear axle spins freely.....If it does start it up & tru throttleing it up. It almost sounds like the enge & clutch combo might just be too heavy. If you bush it by hand....is it easy to move, or does it take quite a bit of effort?

I can roll it around freely. I even put it on a stand with the wheel on the side where the clutch is off and the other wheel rotates. So that said the wheels only turn "weight Free".

This is a simular setup to the go-cart that I had when I was a kid. I seem to rememeber that the clutch was turned witth the sproket out. Yours has the sproket turned in. You may need to check that the clutch is rotating the correct direction. It may work either direction, but I do not know it that is true. This may also mean you will need to move the motor to the side.

After doing a little research, it looks like it doesn't matter which way the clutch is configured (in or out). Does this clutch have the adjustable setup with springs and such? You may need to make sure your RPM and torque range is in check with the clutch setup.

Call Max-Torque if you have any questions at (630) 369-9600!!!

      Passing thought here and thought I'd pitch it to the group for debate.  I'm working through a Kodiak which is basically a Big Bear in a heavier bike and the same as about anything Japanese made for 30 years as far as clutch function and design goes.  This Kodiak is odd though in that the centrifugal clutch slipped a bit with good clutch material remaining and the main clutch pack seems to slip a bit as well at high RPM but also still has good clutch material left.  Much like the Kawa race bikes from what I've read.  Do you think it's an option to add a thin washer to the pressure bolts to put a bit more pressure on the main clutch and force it to use a bit more of the clutch material before having to replace?  There's seriously like 50% of fiber left on the main clutch pack and it seems silly to replace it all before it's truly worn down.

      Anyone familiar with these models? Its a new to me quad, picked it up for basically nothing... Just time and materials now, this looks expensive.

      Hey all new member so I'm sorry if this isn't the correct place to post, but I'm having trouble with a 2000 polaris magnum 500 I just acquired. The quad ran when I got it but was having problems that sounded like the camshaft, and sure enough camshaft lobe was pretty much gone, so we replaced the camshaft and exhaust rockers and now the quad doesnt have spark. We had the quad running right before we tore the old camshaft out and now no spark. Anybody else ever have a problem similar? We've been checking for loose wires, checked grounds, and double checked timing but cant get it figured out so any advice would be appreciated! Thanks

      What is the opinion on carb kits? What's one of the better brands of aftermarket? OEM is always preferred but not practical, chinese cheapie is never a good option. 
      Thoughts ?

      About done with the Kodiak finally. Oldest took it out today and ran the piss out of it, buried it to the belly, and I think its finally about ready to trust. However, there is a clutch slipping that needs to be addressed. It pulls fine from a dead stop to about half throttle. If you go ahead and open it up, the clutch basically lets go at higher RPM. My question then is; centrifugal clutch or main clutch pack bad? I assume since it pulls at low RPM then it's the main clutch pack slipping at WOT. School me though: where does the centrifugal clutch end and main clutch pack begin?  Also added to this issue, he was crusing down a gravel road and all 4 wheels locked up and it died. I assume it tried to throw 2 gears at the same time and locked up. It unlocked though and shifted ok after coming to a stop.

      i have a 2001 suzuki quadmaster 500 4x4 that the primary cvt clutch is rusted on any ideas on how to get it off i want to try to reuse it if possible.

      Recently started shifting hard from neutral to first causing it to stall. I'm able to lift up on the shifter and throttle up and slowly let off the shifter, like driving a standard. That is the only way to get it In gear and stay running. Also if I come to a stop and keep it in gear it wants to continue moving, eventually stalling out. I don't have much experience with the bottom end or clutches. I just now replaced friction and steel plates and that made no difference. Don't know what to do now.

      I just bought a Yamaha Big Bear 350 from 1992. The previous owner has run it on regular engine oil and I have problems with the clutch slipping. I think that's the reason.
      So what should I do?
      - Just change oil and it will be OK?
      - Clean engine/clutch + new oil?
      - Or do I need a new clutch?

      It is guessing the centrifugal clutch that slips. It has two clutches , it also has a "regular" clutch .
      Anyone who has any experience of using wrong type of oil?

      How do I replace the pinion clutch shaft in a 1987 Suzuki LT230 quadrunner? It starts up on the first kick but when I put it in gear it wants to kick up. I can give it gas and put it in gear but my clutch lever isn’t doing anything. SOS
