| Assuming that you've had the hi-comp pistons changed back to stock ones (assuming it had hi-comp pistons) and now it makes 61bhp - it must have made more than 61bhp with the hi-comp pistons, right?
The highest bhp figure I understand was 68bhp.
Therefore, the difference between Geoff's 'imaginary' 61bhp and the top figure of 68bhp is actually 7bhp, and probably nearer to 2-3bhp.
Rattler's 620 literally had end cans and a filter (maybe a PC3??) and that made 61bhp - So I don't believe that Geoff's bike which was built by Baines (arguably the best 2-valve shop in the UK) could only muster 61bhp as well. What do you honestly think?
Maybe I'm just too cynical???
Anyway, it doesn't matter what power it makes, coz you're not out there to win are you - it's all for fun!
