Have a look at this sweet 2-stroke bob built by Scott Towne in his "spare-time". It might have been done before, but this is the first I've ever seen. Much respect for this awesome toy. Check out his blog and link to a Chop Cult article on him.
Scott, you are a modern day pioneer. I want to build a little 2-stroke chop now. I'd bet my botton dollar I'm not the only one either.
In his post he mentions what the hell he would do with a smoker hardtail. Good question but, its the bombbay doors. Cheers for the inspiration.
