Howdy y'all!
I found something suspect the other day while performing a valve adjustment. There appears to be a small, hair line crack near the vertical, exhaust valve guide. Here:

First, I should mention that the bike is a 2004 800ie with approx. 5,600 miles. I put on the last 1,600 miles and have never noticed anything unusual as far as loss of power or smoke from the exhaust. However, I did notice that the valve seal was completely split down one side. Although I cannot say 100% that I damaged it, I was very careful loading the closer while checking.
Anyhow, what should my next step be (besides finding a bottle of Scotch)? Button 'er back up and do a compression test? Leakdown test? Duct tape?
Thanks in advance! [beer]
...and BTW, installing a valve seal on the vertical exhaust side is absolute Hell. ;D
Me?
I'd put the valve cover back on and watch the oil consumption and plug on that cylinder.
The engineers here will tell you you're doomed. ;D
Gotta agree with ducpainter, the alleged crack wasn't bothering you until you saw it. Could be a crack, could be a casting flaw of no importance that was not machined out.
Good point. The plug looks fine other than being a tad lean. I'll keep an eye on it though.
Thanks.

No, we will say it should have been easier to install correctly ;D Seriously though, I agree - keep an eye on it, but that is it for now.
