i do like the bike but a few of the other guys were telling me that it was not the best frame for speed because the way the rear tire is tucked under, it does flip easy as far as he motor i just want to go a lot faster all i have done to it is remove the gov,bigger jet,i did make a pipe for it but it is to loud for where im living now,my top speed was 30 mph and iam 150 lbs or so what does yours top out at with the smaller gear?
