I machined my squish yesterday down to 1.2-1.4 (measured with blue tac so only so accurate!), I was running 0.5mm base gasket before, I've just bumped up to 1.5mm base gasket (to get ports to line with piston flush) and reduced the squish. The difference to the bottom end is insane, far more powerful (counter intuitive considering raising the exhaust port etc benefits higher revs more), BUT, I have actually lost a bit of top end (I did machine out for same cc in head), this has lead me to believe that perhaps before I had jetted rich to compensate for the bad squish (I was running 2.6mm), and now it is corrected, the jetting is too rich. This would bring me to a 175 main jet which is in line with a fair few people's bikes (I would go out and mess around with it now, but I am hungover and it's pissing it down outside
, fair weather much lol!), would be interesting to know if you found the same with jetting?
