OK well, I finally started working on the HEAT problem on my bike you guys would not believe what I found. The FAN is shatered. In pieces behind the Radiator. The Radiator has no, I repeat NO water in it. Don't know if it was from before I got it or not. I haven't had the bike that long. Doesn't seem to be any damage on the back side of the Radiator. The Problem is we can't get what is left of the fan off and don't want to force it. Is it threaded to the cam or is it Just splined on.
