I currently am running a motorizebike with the standard 80cc motor kit. I think these things are awesome wish i had one growing up as a kid. I currently dont have a car and I drive my bike 14 miles to get to school some days and its taking way to long at 18-22 mph 30+ would be awesome. I weigh 200lbs. If possible Im looking for ways to Increase my top speed, and power. I also dont have much money at the time so please the cheaper fizes the better. Please any small tips will help I.E. spark plug type and so forth. I also use the opti-2 100:1 ratio maybe there is better oil out there THX.
