    So I picked up an XR100 engine that I will be rebuilding to go into a YSR frame. I am going to have to fab a pipe for it so I have some questions. What size is the tubing used by most performance pipe builders? I know that the stock sizing is a bit restrictive so I am wanting to build something to open up the engine.

    So nobody has an aftermarket pipe on their XR? I just need to know the ID and length for a proven pipe.
