What do you all think of leaving out the bottom ring on a 201t?

Combustion pressure forces a ring down to the bottom of the ring land and out to the cyl somewhat....by lapping the bottom side of a ring you get rid of the highs and lows and it seals better on the land of the piston....only really works on new pistons cause on used pistons the ring lands are already deformed a little

And I'm guessing you do it by hand and avoid the ring pin?

It's a old Karting trick...I do it to every new piston....it's hard to notice a comp increase....but ya ever notice blowby discoloration on the side of a piston....not sure if it's actually from bad seal on the cyl or bad seal on the ring land
