Bike is a K5
Soooo...I'd never done a valve adjustment on my bike since I've owned it because it never really seemed to need it. I decided to try it today though just because I've put a lot of miles on the bike without checking.
When I got to the #2 cylinder's exhaust valve I looked at the tappet cover and there was no rubber seal. I was staring at the thing the whole way so I can't imagine there was one in there that fell out without me noticing and I checked all around the ground and on the bike to be sure it hadn't.
My question is, if it has been like that all along (thousands of miles put on the bike since) would it be possible for that area NOT to leak under running conditions? There's been no oil seeping out at all but the tappet cover didn't seem all that tight.
Again, I can't imagine there was a seal that fell out as I was staring at the thing the whole time but the slim possibility of a loose seal dropped into the cylinder is making me a bit concerned.
