i heard a rumor that by changing the fan to a 40hp type one can decrease fan noise. anyone know if this is true and how much is involved in the operation? thanks rob.

I had a 40hp fan in my 36hp Okrasa motor back in '69 and it used to whistle at high revs, I was told this was common. So don't know about reducing noise.
Just bolt in a 40hp genny and fan assembly.

jam as much sound insulation into the cavities of the body on either side of the rear windscreen - TONS of noise gets transmitted thru there. trust me. I did it, and it easily cut 1/4 of the noise out.
