This helps and yes. Main jets have been changed. I am going to work on fine tuning it soon and with the main jets changed i noticed a loss of 1/4 to 3/4 throttle. It will rev low with a role of the throttle up to 2,500 rpms then it likes to bounce up to 5,000 and above. So I am assuming the needle is where my problem lies. When not in gear there is no slow throttle response that can gradually rev from 2500 to 5000 rpms.
