+ 1 on that. My riding partner went through 3 HD fans in less than 10k. They would not hold up. Keep the cylinder heads cool and the oil will not get hot, its an air cooled engine. Get both. I can feel the heat on right leg when running the fan but its not bad.

 

I have Rivco air horns in place where a fan would go, and I don't want to get rid of them. OTOH, I've often thought about rigging a small motorcycle radiator fan behind the horns, as that should help at least some. I haven't looked closely, but suspect there isn't enough clearance between the horns and engine, so that may be a weak idea. I've been looking at these fans and there are quite a few available on Ebay, but give only model application, not size. There are also some universal radiator fans, but I haven't found any <2" thick, and that's definitely too big for the area I have to work with inside the horn area. The fan would need to be robust since it will be hot almost all the time and must be waterproof, and I would think a MC radiator fan would fill that bill, but it's a matter of finding one that will fit in without making contact with the motor.

 

Until you put a barrier between you and that air cooled motor you are going to roast your nuts when sitting in traffic...unless you install a crotch cooler do a search we have a pretty good following with all of our products.
Thank You..
