I've read alot,got a donor bike and a 2 stroke China engine so lets see if it all soaked in. The 1st hurdle I ran into was when I found out the front fork on the builder mountain bike was recalled due to fork fractures in the middle 90's!! Contacted the mfg. and now waiting for a new updated front end at no charge. I enjoy light fabrication and design so this is great! Thanks to everyone's input. A big help to us noobs.
