Re: what did you do to your motor bike today?
RC it sounds like you have tried all the tricks with no big gains, my little 48cc runs 25 to 28 cruise speed easy. It may give you a idea what it should run like if you go ahead and put the nt on, I have a nt as a back up and have run it on my bike. I found out what alot of people said about rich jettting but it still ran about 30 wot. With my cns and the copper spacer I got 32.6 sunday on a long flat country road.
Your results may not be the same,Greg
