Thanks a lot for all the detailed info here. This thread is mainly about your 300 head, although you refer to your 200 as well.
I just measured my '15 200 squish to be 1.8mm (OEM setup, doing the bike's first ever piston replacement now).
I haven't removed the cylinder yet, but it sure has a thick base gasket, at least one of the 0.5 ones.
If I go with one .15mm gasket, that should bring the squish down in the 1.45 area, a tad too high I presume (if there is a 0.5 gasket now). However, I do have a lathe (and have cut heads earlier) so if necessary, I'll cut it down.

I thought about aiming for 1.3mm. Should I go lower? I run 98 octane gas (known as Super around here).
What squish height did you end up with on your 200? and what about the CR?
