Welcome to the forums haya. Sounds like you have a pretty mean bike there. You might want to post your thread under the Yamaha topic on the main page. You will get better response than here in the Raceway topic.

 

o.k thanks mate

 

I can bet my left nut that you are running wayyyy too lean! Just a thought though.
