 Which engine for 400ex frame?
Ok guys I need your help. I am close to finishing my 87 250r project and I have another one to start on. I have been given a complete rolling chassis 2001 400ex. The only thing missing is the engine. Now what 2 stroke engine should I put in there? I was thinking of a 250r or CR250 engine. I can get a 96 KX250 engine for $200 that needs rebuilding but that may take a bit more fabricating than I can do. And I thought about a CR500 engine. Steer me in the right direction here guys. Any input or thoughts will be helpful. Maybe a banshee engine???
