When I was working on my R42 last winter I was given some incorrect information on how thick the fiber clutch disc material should be. I was told that it should be 6mm and 1/4" should work. Not so,I ended up using 3/16" thick material to get things to work correctly. I suppose that my clut...

ohh, I was hoping my R42 would sound about like my R60/2. Is it all engine noise or is the exhaust loud also?
