I have been getting knowledge from this forum for a while and decided to sign up today and say hello. Hello! I have built 4 bikes over the last 6 years or so. All 2 stroke china girls of various quality, 2 66cc and 2 50cc. My current toy is one of those 1 piece cylinder/head deals. Cleaned and matched the ports, slightly modded the stock exhaist and put on a 40t sprocket and hub adapter. So far got her up to 33 on a windy day. Hoping to do some more soon. Anyhow.. Nice to meet you guys. If there is anyone in Minnesota, we should ride. I have another friend that I turned onto this world and he loves it as much as I do.
