Default Re: question about 49 and 80cc

Hi Vencent, My 49cc was also easy to start and lacked power. I could lift it by the seat getting the rear wheel off the ground and with the clutch out kick start it easly with one try. However each time I rode it It got harder and harder to start that way, power also improved after each ride. Whats going on is part of the break in process. Each time run your engine during the break in period the rings seal more and more making more compression. Now I can no longer start my engine that way because there's too much compression. I weigh about 180 and cruze at 17mph at half throddle.I read some where on here that there is what they call a death race each year and the last winner was in fact running a 49cc engine, so just give it time to break in.
