Hang on Andy , I am not saying Steve or you are bad mechanics , I paid you guys a compliment in the paragraph . It would benefit all 300 owners if you guys posted up your hidden details of porting , squish , squish band , port maps , timing etc .
Let's judge the guys that have posted about seizing their 300's in this forum .
Let's assume that the 300's that you guys have tested are not correct that's why they only make x hp .
Then why does my bike produce a desired curve on the dyno and reflects an improvement compared to my 250 that was tuned by the same guy and went well for a 250 .

*Andy , you are misquoting there *
