Interesting, I have pondered this. Merc crank in a 21stud. I know the increase in seat of pants power is very noticeable when you bore a 21stud to 3 3/16". Often thunk is it bore increase or stroke increase that makes more difference? Both is obviously good. But if you had to choose, what would it be?
Just idle thinking really.
any thoughts?
