Whats up all, Today I was doing a shift pro and shift star mod on my bike and when putting the clutch basket back on I noticed there wasn't an o-ring installed behind it. The clymers manual shows one on page 156 it is the #17part. Is this o-ring really needed and for what purpose? I was wondering if I could just leave it off. Thanks!

i don't think it is necessary. i think it is meant to dampen noise or keep from getting stuff lodged between the basket and the gear or something. maybe somebody with more knowledge than i will chime in and tell me if i am wrong.

i wouldnt worry about it. ive never put one in there.

Thanks guys for the quick responses! Obviously the factory didn't put one in there when they built it, I looked for it high and low and still couldn't find the damn thing. :biggrin:

yea i always leavem out also, they are suppose to dampen the clutch chatter noise.. let me know how u like the shift pro combined with the shift star.. i did the same to mine and its awesome.. everyone likes something different though.. its definately worth the time and money

I am hoping that doing these mods will help with the mis-shifts between 1st. and 2nd. gear. I hate when that happens!

man i had just built a cub motor with 33 pwk's, cpi inframes, and bll the other goodies.. right away i had shifting issues (imagine that), i put the star and shift pro in and wow, its a huge difference, smooth effortless shifting.. not as good as an overide of course but its way easy to shift.

rudedawg,

 

i have seen problems not using the oring if your running a bone stock clutch and oem plates. i have also seen guys not have a single problem. so its kind of hit or miss.

 

also if you have aftermarket plaes you dont run the oring.
