Does that mean it is a metal gasket? What implications does this have on resetting squish?

They are rubber o rings.

OK - so no gasket, just the O-rings?

So my mate is copping flak for wanting to check his squish first before jetting. How likely is he to find bad squish measurements? How much difference does setting up the squish actually make?

I thought setting squish was step 1?

I'd say step 0 actually. It's being done.

Haha ya jerk

I did the other day on new 125 top end. 1.2-1.3mm as using 0.8mm base gasket. Bit big but will chuck the 0.3/4/5mm base on for next piston to get it down to 1mm

300 never really bother with but will next top end(soon) & 165 was already pre set
