I just bought a 4-stroke chain drive Gasbike Storm 49 cc kit from craigslist new. The seller decided that he was not mechanically inclined to install this kit and it has been sitting unused in his closet for the last 3 years. I jumped at the $125 price after researching motored bikes for the last few weeks. I initially wanted a motorcycle but wifey nixed that idea. My last bike, a '75 Honda 400F was sold to buy my wife to be an engagement ring many years ago. I looked at scooters but they were so pricey and the 49cc models were too slow. Looking forward to 2 wheel motored riding when I get this kit install.
