What in the world would you need to modify on an 1125 engine to make it a "race bike"?
Does any have any CAD or technical drawings they are will to share on the 1125r/cr or the Rotax Helicon? I am looking modify mine to become dedicated race bike and starting with some reference files would make life a lot easier.
