awesome little bike---you will love it. the first thing is to remove the rev limiter above the battery . it is easy to do . the next step to get some decent performance is to install our %!¤pipe exhaust, a better air filter and rejet the carb. this is all very easy to do for someone with basic mechanic skills, and it will greatly help the very heavily restricted engine perform up to its potential. if you really want to make it rip , the 88cc kit we have is a 60mph upgrade. all the parts are on our store page at www.moto-scoot.net madass fever strikes again!!!
