Hi all, Im just about to buy a new crankshaft and wanted to know want sort is best for a malossi 210 worb5 modified, on the standard rotary valve carb set-up(28mm carb). 57mm race or 60mm?
Thanks[:O]
Generally, the best crank for a 210 is a std crank, if using crank timed induction. They are stronger but you will have to modify the timing. By standard im talking GENIUNE PIAGGIO, not PATTERN. for reed induction with modified porting to suit, use a reputable tuners full circle crank. I have done a similar crank as worb5 special lip and the balance was horrendous. Yes i did gain hp but engine longevity is preferable.
