clutch problems

[MILO]

i recently put on a hinson basket, tusk kit, new inner hub and pressure plate. thanks to everyones help, everything went well with the rebuild. but lately it's been acting up. when sitting still in gear, if you rev it, it wants to roll a little. i had the arrows on the case adjusted properly before, and it worked fine, and they still seem to line up right with good freeplay. sometimes it feels like it binds up and is very hard to pull also, then smooths out again. i cannot see anywhere that the cable is binding or kinked. it's also still the stock perch/lever. it's not slipping at all, just rolling a little when revving. when all the slack is off the cable, the arm at the crankcase doesn't always return fully on it's own, but has to be pushed by hand. any ideas with what's going on in there?? thanks.

Does it still want to roll a little once it's warmed up? Mine would do that until I rode it and warmed it up, then I wouldn't have any more issues until it sat and got cool again. When you installed the tusk kit did it come with aftermarket clutch springs? If it did, and you installed all 6 of the aftermarket springs, that would be why it's tough to pull the lever. Try adjusting it more at the perch and see if that helps your problem with the arm not fully returning. If the arrows on the case are close to matching then you should be fine on your adjustments inside the clutch cover

i did use all 6 of the hd springs, and i can handle that. it is a little tighter pull, but i mean something binds up and it is very hard to pull, like it would snap the cable before pulling in all the way. but then it frees up and it's fine again after playing with it a little. that's happened while about 2 hours into a long ride. it tightens up, then fades out again and works fine. i didn't really notice the grabbing when sitting still until today, and it wasn't really warmed up well, but i never noticed it before today when cold either. and i didn't want to run it too much if something else was wrong.

when it's adjusted properly, and the clutch is released, how far should it return versus the arrow on the crankcase? mine goes back to slightly beyond the arrow. with the adjuster at the perch loosened, you need to push it back by hand to get it all the way back again. i thought it had more spring action before and went back that far on its own. it's just acting different than it did after the rebuild. that's what has me worried.

Your transmission oil has alot to do with the cold and warm thing.Oil shear clutches tend to creep when the oil is cold.This is normal,as the oil warms up it causes less friction between the floating plates,eliminating the clutch drag.

 

The next thing I'd be looking at if the adjustment is correct and the cable is good would be the pushrod and ball.

 

Your problem might lie in the clutch arm were the cable hooks up to.Theres a bearing in there that may be partially frozen,or the shaft might be gored up.I had a similar problem with the the shaft, it had wear marks from the rollers in it.

i thought i could rule out the push rod and ball since the tight binding was only occasionally, not constant. i may rip it down just to have a peek anyway and see if anything else is out of sorts in there. the clutch arm bearing sounds like a good possiblity though. something is definitely binding at times and that would make sense.

thanks guys.

ok, i just got into the clutch and everything looks fine. the rod and ball are fine, and nothing else even shows any signs of wear yet. so... i'm gonna double check the adjustment before i throw the side case back on, and look into other things. like the arm, bearings, cable, etc. again. at least i know that all of my recent clutch work is still cool and in good shape. process of elimination i guess, and i'm very happy to eliminate the rod/ball, and the clutch itself.

is it possible that it's just the clutch cable is stretched and needs replaced? if i really adjust it out at the perch, it stops creeping when sitting still and revving. there's no play and it is a real bitch to pull then, but it shifts smooth and doesn't creep. it won't pull in to the bar either, about 1/2" from it seems about all it will go.

Check that your basket bushing isn't seizing to the shaft.
