I just heard that there is 3 different model 20B Cosmo engines. Is that true?

If so, what are differences between those models?

Help? :)
Power is nothing without control. Weight is enemy of performance, handling and braking.

All I know is that the best one is the "C" marked castings, much stronger, won't break etc, other prone to bearing failures and cracking when asking for more power
