I recently put a 15t sprocket on my SH. It turned out to be more of a project than I had bargained for, but once I got the bolt that I broke extracted it wasnt so bad. Anyhow, my question is this. The OEM sprocket had a rubber gromet sort of thing around that actually is part of the sprocket. Should I cut it and try to put it on the new sprocket or should I just install the new 15t as is?

 

Install as is. It's too dampen noise/vibration and isn't removable. AFAIK, only the stock units are like that.

 

cool thanx. I just got done installing it, ended up keeping the same chain even though a new one came with the kit. I thought the 2 up in the rear dropped some ballz in it but that def did the trick. Thanx for the input

 

If you've got more than 10,000 miles on the OEM chain, replace it with the new one you have anyway!
