Ok, I've got some miles on the 103 stroker build and I'm noticing a significant vibration of the bike while under hard acceleration in third and forth gear. This is probably the clutch slipping a little bit as I have noticed some definite slippage when hitting 5th.

I've been looking at possible replacement clutch plates but without an objective review, I really don't want to rely on the manufacturers say so that their's is the best.

Any suggestions that I might consider?

 

Not sure about the differant plate material helping. After I did my 103 this winter my dyno guy showed me on the print out where my clutch was slipping so I went with a ProClutch. A lot more plate material then stock and it shifts smoother.
My numbers from the dyno are 118 Hp and 113 T

 

+1 rivera pro clutch is the only way to go
