Thank you for the feedback, it is just a stock cylinder I'm bored and playing around with. Half of my reason for this was under piston cooling, but running the transfers all the way to the cases negates that. The other half is I wanted to aid scavenging at low end and increasing transfer area a bit, possibly aiding in top end power.

I'm trying to get the most I can out of just stock maxi parts aside from a 25mm puch header from treats. The starting combo is high torque cylinder and head, 2 ring dykes piston, bing 12 carb, bing 14 intake, stock air box, and something cobbled from a stock exhaust can that looks stock.

So far I've widened the exhaust port 2mm each side and went up 2mm, might go to 3mm up. Matched it to the 25mm header. Going to stack thick base gaskets for now to, with compensation for gasket compression, to add another mm to exhaust and transfers. Piston edge with .5mm gasket is at deck height so I'll be sanding the head to ditch the factory recess and running no head gasket. Theoretically I should have 1mm squish.

I have the expected port timings written down but I locked up the garage for the night, I'll post them tomorrow when I get out there.

Anyway I thought of a new idea.

I could feed these with corresponding holes in the piston outside of the intake window. Hopefully succeeding in both of my reasons for trying this. (edited)
