The new 2004 version CMB.45 RS look like strong beef crank . Will find out later because the CMB factory already built and will possible sell them first March
I bought the 2003 model last year, and the first race I went to, the needle bearings siezed. I spoke to Bobby and he said this was a freak accident. The motor was great up until then. (many days of testing)
Anyway, I had the 2003 upgraded to a 2004. It requires a new crank, rod, drum/housing. I haven't ran it yet due to hard lakes. I can't wait to run it though.
