Ok my bike just recently started this. In first, second, and somtimes 3rd if i go WOT or near WOT the bike kinda bucks kinda rythmicly while it accellerates to redline. Kinda a hard buck and clunk. Just wanted some ideas on what it is...bike drives normallu otherwise.

 

Tighten your chain. I have the exact same bike and had the exact same problem.

 

thanx

 

Yea that was it alright...drive splendid now : )
