i think the happiest all around rear ratio in a turbo fiver would be the 346.

i had my 240 fw checked for balance. it is neutral.

on my 300d euro stick (83) we had to change the crank so there was no possibility of any marks. although we searched for them diligently. so finally we just bolted it on at random. it was smooth as silk. this was before i knew that the fsm suggested balancing with the crank.
