so my bike got stolen last year, had a 66cc in a cheap walmart mongoose full suspension but had to fix the rear suspension, it was loads of fun after breaking in & extensive test & tune. so this year im going for faster & better, having said that, does anybody know of someone that modifies or upgrades internals on these engines before selling, after a lot of web searching ive only been able to find a guy that used to do it a while back in canada, chriss hill(ch80). well if any tips or info, thank u very much cause i cant wait to own the rds again on my bike.
