[QUOTE="Binky, post: 737100, member: 33711"] And since your bike is already an 85... your stroke increase would be zero. duh. No overbores allowed in AMA for displacement classes this year. period. LL or anything AMA. Your options are porting the cylinder, cutting the head(minimal improvement), a pipe/silencer(minimal) and better gas. I have NOT worked on the RM85 so I can offer no specifics to the bike. [/QUOTE]
