Re: Top Speed
Checked my spedo today and it says my top speed was 36.9MPH, that's a little bump from 34.8MPH where it had been sitting. Really, I find it hard to find places to go that fast safely...
I have a stock Grubee SkyHawk GT5 66cc kit with CNS carb on a late '80's Specialized 26" wheel Mountain Bike, only motor upgrades are the NGK plug and a quality plug wire. I did a lot of carb tuning, including opening the main jet up from the size of a #72 drill bit to a #69. The rest is stock, exhaust, rag joint sprocket etc. I have about 250 miles on her now and am running a 32:1 mix with standard 2-stoke oil.
