so far ive got a 70cc malossi cast iron bore, sh*tty technigas exhaust :banghead: going to get stage 6 pro rep :grin: , and its de restricted, everything else is standard, im thinking of changing the crank but wanted to no if a full circle crank would give me much more power or if id be better of just getting a standard and any other info on what to get for max speed would be much appreciated
If you replace the crank it's pointless to fit a standard ones. Pretty much all aftermarket cranks are full circle. They give more primary compression. You don't actually have to replace the crank as you only have a sport 70cc kit.
