Re: Helio (hello) from San Diego!
I like most went with the two stroke because of price and the power of the 48cc engines. The only legal engine here is 50cc and under and has to be one speed, after having many motorcycles in both two and four stroke I knew I could do a little work on the two stroke and increase the power. I have had so much fun riding I wish I would have built one sooner, I still have the first one I started in late 2010 and ride it regularly.
Your results may not be the same,Greg
