View Full Version : Request: Top-end tutorial?

I was wondering if someone could document the top end work next time they do this? Hopefully, I'll be able to study it before I have to try it myself for the first time.

I have a manual, and seen the two top end threads on barf, but I would really appreciate a Derbi-specific example for extra insurance against screwing my bike up... :D

Please?? Thanks!!!

There is a full rebuild on a derbi motor that will help you out. It is a very easy process.

This is absolutely great, guys.

An online forum/community has such an amazing potential for a wealth of knowledge. It's nice to see it working so well here at BATS.
