Os 77
I have a brand new one, with the RPM rod. Large head, going in a Byron F86D. Two questions:
What should the pipe length be with the stock byron pipe for the 77(square end)?
How does this compare, power and reliability-wise, to my OS91's? The 77 is one of the few DF engines I have not mussed with.
