im leaving it where its at i think. i tried up jetting and lost alot of performance. almost 4mph top end. i went to put my 70 jet back in and i dropped it and it fell through a crack in my driveway!. oh well better get on treats and order one.
why is there such a big differnece in jetting between a 14mm bing and a 15mm bing? is it the jet holder and needle they use? i cant see it being much of a differnece in 1mm .
