eagle Posted May 13, 2007 Report Share Posted May 13, 2007 I just bought this bike and it has issues. Feels like clutch slip in any gear but I cannot find a damn thing wrong with the clutch. I have been all the way through the tranny trying to find this. Feels just like clutch slip. Very smooth and pulls fine until it hits the power band. Things I have checked: sheared key on PTO crank gear, sheared bolts on clutch basket, made sure pressure plate was not bottoming out, springs are more than enough to hold the power, clutch pack is brand new, trans is good to go, axle hub splines look fine, sprockets are fine. I just cannot see a damn thing wrong with the clutch and made damn sure the clutch arm and pressure plate are allowing max engagement. What else is there??? I am ready to pull axle bolts and see if the sprocket hub splines are shit. That is a long shot and it "feels" like clutch slip. I am about ready to just throw in some mack daddy clutch springs and see if that changes things. At least it would tell me if it is the clutch or not. Any other ideas???

Any other ideas??? whats your tranny fluid look like. My plates used to stick together and it would slip a bunch till it got warmed up. It ended up partially being due to improper adjustment even though it seemed like it was engaging all the way. After awhile I ended up with gray fluid and needing new discs. It would pull hard down low but just not pull hard mid and up till it was warmed up then after awhile just started loosing it all together.

bbluebanshee Posted May 13, 2007 Report Share Posted May 13, 2007 You can usually hear this, but how are your sprockets? Quote Link to comment Share on other sites More sharing options...
eagle Posted May 13, 2007 Author Report Share Posted May 13, 2007 You can usually hear this, but how are your sprockets? As noted above, they are perfect, fluid is brand new but I am sure if I ride it like this, it will be gray in no time and my plates will be toast. It is not right and I am at a loss right now. I could almost accept that the clutch could not hack it if it was some 135HP stroker, but this thing is only good for about 80HP. The clutch in it should be good. My fluid is Belray 80W. I have used it before with no problems. Quote Link to comment Share on other sites More sharing options...

So smooth, it just has to be the clutch but damn is it kicking my ass. Quote Link to comment Share on other sites More sharing options...
dawarriorman Posted May 13, 2007 Report Share Posted May 13, 2007 The adjustment at the engine won't really do much for slipping as long as there is slack in that lever. What kind of terrain are you riding in that you're basing this on? Take it out on asphalt and ride it. Its a really distinct feeling on asphalt when the clutch slips. You said the clutch is new, what about the springs? Are they heavy duty? You can get springs that are stiffer than the regular HD springs, throw 3 of them in there. And what kind of tranny oil are you using? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted May 13, 2007 Report Share Posted May 13, 2007 i hate to tell you but if the motor is older and the clutch parts (inner and outer hubs, and pressure plate) are worn out and grooved, it will toast a new clutch pretty quickly. sounds to me like you know what the problem is (slipping clutch). i bet you need to replace all clutch parts and the clutch itself. 80hp is plenty to toast a normal clutch, especially if other parts are bad.. i say pull the clutch apart and check the parts themselves. see if they are grooved and worn out. if so call FAST and get the parts and one of his clutches and youll never have another problem.

Clutch basket is a brand new Billet, new inner hub, new plates, new springs. I have never seen this much slip before. Quote Link to comment Share on other sites More sharing options...
theshee Posted May 13, 2007 Report Share Posted May 13, 2007 Just put a new 39 dollar tusk clutch in it. For 39 bucks thats a pretty easy place to start and who knows, it may fix it. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted May 14, 2007 Report Share Posted May 14, 2007 if its your clutch, theres a reason its slipping. is it not properly adjusted? i wouldnt think at 80hp with all new parts it should be slipping, but i could be wrong.

eagle Posted May 14, 2007 Author Report Share Posted May 14, 2007 (edited) if its your clutch, theres a reason its slipping. is it not properly adjusted? i wouldnt think at 80hp with all new parts it should be slipping, but i could be wrong. You bet I am pissed right now. I cannot figure out why it would be slipping. I even installed three barnett HD springs and three standard springs by ME and that did not hold it back. I know adjustment is right. I think it is time to hook a DAQ system to this and verify the clutch slip. I guess then I will know and where to go. I know this clutch I have will hold over 100HP so this makes no sense at all. The only thing I can think of is friction plate contamination. Man this one is beating me for sure.

dajogejr Posted May 14, 2007 Report Share Posted May 14, 2007 Take it all apart, measure the thickness of the plates and the fibers... I used 3HD springs and 3 stock springs on my 4 mil cub...quite a bit more than 80 HP...and it held up just fine. Even a shitty clutch should hold when new...if only for a little while. Is it possible your cable is shot? Stretched out..??? The arrows on the arm/case line up with pressure from you pushing, and you're leaving a nickel width gap at the lever/perch?? Did you put the right number of fiber/steels back in? Did you put them back in correct order? I know they sound like dumb questions...but you've answered the tougher, more common ones. Now it's time to look for something a little more off the wall... Quote Link to comment Share on other sites More sharing options...

dawarriorman Posted May 14, 2007 Report Share Posted May 14, 2007 Don't focus on the adjustment too much. As long as you can push on that lever (the one on the case) and have some slack, the clutch is fully engaging. If you can't get any free-play, then the clutch isn't engaging fully. That adjustment is really only adjusting the length of everything that pushes on the pressure plate. Go past the arrow, and you can take that all back out as long as there is enough adjustment at the lever. What kind of oil are you using though? Are you using an automotive oil? Some of those will cause slippage in a wet clutch like bikes and atvs have. Did you line up the arrows on the pressure plate and the hub?
