Leaking from the head gasket, a little on both sides right below the bolt in question and right where the o rings are.

I put them in along with a tad of sealant, but I was worried they looked a bit small.

The gasket kit came reccomended from a couple good sources so maybe I just screwed something up.

It leaks enough to drop one drop down onto the starter every time I take the bike out.

I assume a long ride would generate much more.

The o-rings looked small in what way? They're 11x2 and should just fit over the knock pins and inside the larger holes in the head gasket. Not sure about the issue with the 6mm nuts at each spark plug hole. Is there oil around the base of the spark plugs? Sometimes these motors weep oil in that area where the steel domes and aluminum casting meet.

They just looked a bit thin.

I had a long talk with LM on this, and am going to do some more cranking on the bolts.

I only had four of the special locking washers, and I think I put them on the inside rather than the outside.

Need to check it.

Check to make sure the studs aren't too long, and bottoming out inside the acorn nuts.

Thanks. How would I discover that?

Run the nut down on the stud without the flat washer. If the nut will just about touch the head without the flat washer under it, the length should be ok.

Thanks. I cranked them all to 23, so I am going to see how that goes and then consider other options.
