First off... I'm only trying to get 40mph average outta this little guy.
I bought the Amazon cdi kit... And a ngk plug... And tuned the a/f and idle on the carb. I still am stuck at 35mph... Although I did max it out at 39mph at some point according to my data logger. Checked the speed with gps app and speedo. I start hitting 35mph and it start sputtering. My guess the cdi is maxed.
So I was thinking maybe buy an adjustable cdi, but I don't want to over rev it... Or rev it past it's power band. I mean if the little guy is making peak horsepower at say 7k... Then there's no reason to rev it up into the 9k's.
Amstar is useless. I emailed them about replacing the brakes and they emailed back saying "what do you mean?".
On another note.... Anybody know how a 70cc kit gets installed?... I'm thinking that going to be what I need to get to a solid 40mph. Or maybe a carb upgrade? IDK. Any ideas?
