Hobbit athena piston windows

Terbo Speghetti /

Do you do em? Can i see?

I like to window all my pistons, but Athena kits don't even come with the lil bb holes drilled in the side of the piston.

What gives? Is there some benefit I don't see? Seems to my untrained eye like they're leaving a lotta charge on the table (edited)

Hmm never experienced lack.of.power with my setup. Don't especially need more. But hey that doesnt mean shit. Go.for it but remember u don't want issues with overheating or anything that messes with that nikasil . Unless u have a very large checking balance .

Lol @ "go for it"

I don't need anyone's permission, I'm looking for actual knowledge backed by theory. Thanks though, I'll be sure to watch out for my nikasil.

If it were me, I would put the piston at BDC, park out the through-skirt hole onto the piston and cut that first. This is what I have done on my Derbi Metras and it works very very well.

I will suggest windowing the piston versus slotting it all the way through. The imbalance and rocking from the slotting wears everything pretty significantly.

Windows always perform better then non windows.

Not as important on a case reed but still. Helps if there's a hole or cutout in the cyl skirt tho to aid flow into the boost
