[fcerrone]

Well was getting on the freeway the other day got on it pretty good and bike lost power pulled over and quit running.towed to my shop and found the front cylinder @ 0psi compression,exhaust valve hung open .the exhaust valve must have seized in guide and made slight contact with intake valve! Has anyone experienced this bike has 21k on it has been babied since new!
The good news is now I am upgrading to the Screamin Eagle 117 kit. Parts ordered today will put it together next Saturday! can't wit to see what the new dyno numbers will be!

My last build nearly did that. The exhaust valve seals were toast and the stems were starting to stick from carbon buildup. The big bore engines (over 103") with high cylinder pressures operate with reduced spark advance to avoid knock and ping. As a result, the fire is still burning when the cylinder exhausts. This gets the exhaust valves really hot.

You can see the carbon build up on the lower part of your valve stems.

Good luck.

A lifter would have to stick in the lifter bore to do that. Did you check the liter bores and put in new lifters?
