thanks for all the info guys,, based on what you guys said,, and after alot of reading i think im going to clean the exaust, a smaller sprocket on the back, yea i heard what someone said about how i wont have enough torque to reach top speed,,, buut thats what the pedals are for... and hopefully get the carb adjusted right( fouls the plug, needles a tad bent too). i was dreaming about a new engine, but like everyone said,, the cady isnt worthy enough for it.. i was also thinkin bout some white mag wheels for style points, and a milk create on the back for when i go for groceries. hopfully i'll be able to squueze a km/h or two from that smaller gear ratio.
