i got to thinking this morning (dangerous, i know) about maybe going with increasing the compression on a stock bore (.75mm oversize) to work better with the ported head and cb750f cam i'm planning. the question is, can i put a cb750f2-f3 piston onto the k motor with the 75 f0 head. i imagine i'll have to do some flycutting to the valve pockets. any idea what kind of compression i'd be looking at with this combo? (75 750f head with some port work)
