hairline crack on bridge
I have a cylinder that I would like to use but has a hairline crack in the liner right in the middle of the bridge.
Will the crack cause problems? I would think that if it had proper bridge relief it wouldn't- hoping to hear some other opinions.

not sure, prob not if its done right.
ive noticed it happens on bores 90mm and over. ususlly when it gets bored over the scollops it cracks. its an observation ive noticed, maybe cos the metal bore thins out too much or something.
on that picture you show there, it looks like the rings have worn out on the bridge causing the blow by above it

We've been testing two years and have had little problems with removal of bridge.The thing is you have to know how much and where to size the exhaust port to much excessive ring wear not enough loss in top end,just right Rings and piston under normal riding should last a long time.Even Honda say's own a stock engine change rings after 6 races,And a new piston when mesurment are out of spec.

The piston appers to be smered all around ,The top ring is stuck way around. Show the exhaust port, I like the Idea of no bridge it works for us and most race engine porters.Glen

my '86 engine is bridgeless, you gotta make the port easy for the ring to come onto, not flat accross it. no probs here, stil got all the squeeze and its faster than my other stuff
