the raptor, the yz450, and our beloved yfz450 all share the same sprockets.
i think timmyboy was messing with tintin b/c this topic has been discussed many times on here b4..
note to tintin: before you ask a question, make sure it hasnt already been answered on here b4. :stupid
I bought a Raptor sprocket and it is different than the YFZ sprocket. It is flat and does not have the grooves cut on the inside. I ran it for awhile and it started to wear my chain and the guard on the motor. When I spin it I can hear grinding from where it touches the motor. Am I doing something wrong?
