Hey everyone, I've been going through the forums for a couple weeks now reading and gaining knowledge. I've Acquired a bike and engine, although I think the engine is too big.. Here is what I found about the engine.. http://www.orientpowerchina.com/productshow.asp?ArticleID=89 Came off the 3000psi model.. I stuck it in the frame and it will fit but it sticks out the sides far and the crank will spin the opposite of the way I need it to go. Here's a couple pictures, maybe you guys have some idea's? Thanks!!
