Aloha, I am thinking about buying a 42mm full circle hi rpm
crank for my Minarelli Horizontal engine.
I figure it should fit with the minimum amount of "Carters"
grinding and with some alum base spacers to get a .6mm squish,
it should be an easy install. I also would get 5cc more +rpm+ higher
crankcase pressure.
The crank is advertised for Yamaha Zuma Jog, Eton, ATV's.
Anyone know if it is a direct replacement? Will the taper on the
magneto side of the crank be the same? Ideas anyone?
Or is it better to just do a 47-48mm crank? How about the spacers...easily
bought or fabricated. Whew....
thanks Frank
