95 Vmax eating roller bushings?

Why does my primary like to wear out the roller bushings? Sometimes it only takes one ride! The collars look good and they roll nicely when I put new ones in. Also, what kind of damage can be done to the clutch when riding with a bad roller?
Thanks, FishX
 
I once purchased a V-Max 600 XT 96mod who also ate rollers. Fit new rollers, rode a few kilometers and they were busted again.

The problem (I don`t remember if I was told by some guys here at the forum) or if I made a theory myself, was that the "main bushing" inside the moveable sheave was worn out, so that the sheave could move uneven, and since it didn`t move smoothly the rollers got bad very fast.

Try grabbing your outer sheave and press it in, see if you can "rattle" it from side to side, there shouldnt be much freeplay.

I sold my XT to a friend and then we installed Comet clutch, naturally no more worn rollers hehe:).

PS. I`m not a clutch specialist so tell me if if my theory is wrong.
 
It has the stock exhaust. Call me crazy, but how would pipes wear out clutch rollers? I'll check the main bushing but I think it's fine. Could the problem be a flat spot or groove on the weights?
 
Been waiting for you to chime in Daman! I just put some good weights in at the end of last season but I'll have to check them again. Getting kinda sick of replacing those darn bushings! Might have to spring for the kit that gives you new rollers, bushings, pins and bolts. It does not run bad when a roller bushing wears out but I'm thinking it might cause a flat spot on the weight and those are not cheap.
 
I'd tear that clutch right down and inspect every single piece of it,
you got something going there that's bad.(check roller pins close)

good luck keep us posted..:)
 
Take the spring out and check for too much slop in the clutch busings (as posted above). Check all parts to spec. If something is chewing up the roller bushings it could be causing other damage that you cannot see yet. Look for any hairline cracks in the clutch sheaves.

It may also simply be a case of harmonics, although unlikely as Yamaha will have designed the setup to avoid this.
 
yup sounds like you have bad bushings in that clutch, the cover bushing and sliding sheave bushings should definately be your first suspects. That being said, the twins do seem to be much harder on clutch components than the tripples, like Ding said im sure its a case of harmonics and longer distances between power strokes putting more stress on the components.
 
Bringing this old thread back to life. You guys were right. The cap bushing gave out and broke an arm off the spyder. I guess I heard ya but didn't listen!!!!! I've got a nice Comet 108 EXP on the way. I got the Comet for about the same price it would be to rebuild the stocker. I've heard good things about the 108 EXP, I hope they are true. I found a slightly used 108 EXP for $150.00 already set up for my machine. Any tuneing tips???
