Yeah without making a forming tool for this one time job i have no way to manually match the piston curve but i measured the piston with a t-bevel and it lined up pretty damn close for the 5mm of area its squishing.
Hopefully this will be much better than just slapping the head on with no modification. I still have about 1mm of material i can take off the deck of the cylinder while keeping the C/R under 10:1, but i will revisit that after the engine is broken in if need be.
Currently waiting on my replacement ring to show up so i can gap those and finally get the head studs torqued. Then itll be time to set up the CDI and hope she rips.
The engine was described as looking like an angry blender today so thats what my moped is now powered by.
