I agree with you pat i have seen alot of your conversation and comments i know you know mopeds in and out. I weigh 185 6ft and stock a35 is poopy but dependable i agree. Ive learned alot this passed 2 years and ten thousand miles. Ive rebuilt the stock top end 2 times and on my 3rd pipe and just put a new carb on. I have confidence in breaking in a 65cc kit. I would do the start and cool technique and drive her easy few hundred miles. I broke in a stock cylinder and new piston and rings a few hundred miles ago and the piston and bore are smooth and pristine. I think i might do the kit ill make sure i run it rich through a long break in and cool down. I don't drag race or mistreat my moped. I think it will be a good thing. Thanks man.
