Ref. crank, yes you can lighten it, ROAR rules have no restriction over moding cranks, they are similar to IFMAR rules....but wacht out for balance.

Hello afm,
I'm sorry, I did not have the chance to measure the stock exhaust port. I got the compass after I did the mod to my engines.
Thanks for the info on crankshaft.
