Oh dear,
I was thinking that if I have to do anything more serious than the head on my RGs, then I would probably put new pistons in to lower the compression,I was always under the impression that the motor will run a lot smoother etc, or is that not correct? I'm not really interested in hammering the bike 'till she blows up. (In my past life, before migrating to Aus, I did 20yrs as a copper in the uk, mostly on traffic division, on cars and 'bikes) dont need to thrash about these days.
