Pointless exercise thinning out the bridge so much, the intake windows in the piston will act as a leaf edge wall.

But I ain't Never seen nothing like that

The old hot rod saying of "Gotta grind 'em thin to win" even has it's limits 8-|

The reason you cannot see it is because it has dissapeared as grinder dust, there ain't nothing left to see.

Is that a toothpick or dental floss? Do you think that intake bridge flutters in the wind and make a flapping farting sound?? lol

I see that snapping off into the motor. I don't see that being good for the rings ether.

The rings Never go that far down, except during catostrofic failure

This looks like a case of home porting gone wrong. Thats about the size of drag ported 23cc motors.
Sure it might support the piston and rings for a lil while but after that....

 

[Awk08]

anyone wanna buy the porting templates for this ???........

if i remember right, KOR did do a cylinder where he removed the bridge. i believe it ran fine.
