15/36 would be all top end i would check your jetting. 14/38 is stock gearing. i run flat track and run 14/38 on short tracks and run 15/36 on the half mile tracks. i would guess you are both lean on top end im dropping down because of a rich condition from a 175 and 4th notch on the needle to a 165 main and 4th notch on the needle.
