[QUOTE="canyncarvr, post: 655811, member: 16552"] re: 'I just can't figure out why I loose bottom end...' 1. The pipe you chose. 2. The jetting you are running. re: 'why I can't dial in the present pilot jet with the easier flowing setup..' 1. Because your present pilot jet is probably wrong (see above). If torque is what you're after, I don't know why you chose a -30 pipe. The RB mod will improve both bottom-end response AND provide a more linear response throughout the lower throttle postions. So will a good reed system. So will a final drive ratio change. BTW...'gnarly' used in reference to fmf pipes doesn't tell you a thing (regarding performance profile). Removal of any restriction on the upstream side will reduce the pressure differential the carb works with resulting in an overall more lean condition throughout the throttle range. Not necessarily lean.....but moving in that direction. It will effect every circuit in the carb...and the way they relate to each other. [/QUOTE]
