I don't know about the fan and cover status. I do however really like the new 4-Pro clutch for the Rhino. I've installed 4 of them now and they work really well. They also seem to be a little quieter.
have you ever seen the clutch that's on the rotax, it is a dry clutch and I can run with the cover off and it makes almost no noise. WOnder if it would fit pdm's plate?
