blown head gasket
I have an '07 Ultra, bought it new, all stock with about 25K miles. Riding to work Friday morning and the rear head gasket blew out to the point you could see the light inside the cylinder when it was idling. Never skipped, changed idle speed or squat. Any thoughts?

Something does not sound right. Are you leaking oil? I know CVO110 gasket failures result in loss of oil from the return galleys from the head to cylinder. If you could see the cylinder you would not have compression, thus the coil will not fire, due to the ion sensing technology. Yet you still will get fuel and have a fuel smell, or at least a wet plug. It would really miss as well..

I would have thought the same thing about the skipping, but it never missed a lick. It did smoke the outside of the cylinder, but that was all. I was on I85 going into Atlanta in morning traffic and never noticed a power loss or anything, thats why I thought the exhaust pipe cracked. I could hear the whistle but that was it. Tech at the dealer said it wasn't that unusual for a head gasket to blow but it was weird that the engine continued to run like that one did.
It really concerns me that this happened, cause less than 5K miles back the conpensator came apart. Not came loose, but the outer edge seperated at the seam and hung up on the primary case and shredded. Really makes me wonder if they built the engine on a Monday after a big weekend. Other than these two things the bike has been great, no other problems, but damn these 2 things are pretty major in my opinion. What say yee?

I noticed mine after I was done washing it, blew it off with air & fired it up to pull it into the garage & noticed something by my left leg. It went away after a few seconds on a cold start up. It was also starting to chirp when I started it on a cold start for about 10 seconds is all. Never got oil until I showed my wife what was going on, had her put her hand where it was leaking, fired it up and she got oil all over her hand. But as far as the light at an idle at night, is there any air coming from that area? You should be able to hear it & feel it if itis that bad.

when my head gasket blew it ran fine just sounded like to pipe came off is all. So yes I say head gasket blown. Air cooled are infamous for this in the rear cylinder due to it not getting as much cooling air.

There is no doubt about the gasket, I got the bike to a dealer and he pulled the head and I saw the gasket myself. I just wondered if anybody else ran into this. Also. whatcha think about it effecting the overall bike as far as something later on. Warrenty runs out in about 2 months.
