I got one kit about a month ago and put it together,sold it just like that.It ran great but,of course I want to go bigger and faster.I also ordered a pocket bike motor to put on a schwinn S750 electric scooter.Just put together a skyhawk gt5 with the cns carb! This forum realy helped me figure the tuning out.http://motorbicycling.com/images/smilies/wee.gif
