Water coming out of head bolt

Back together after complete rebuild, I have antifreeze leaking from one of the head bolts. I'm guessing the new head gasket was bad somehow. Anybody else have this problem?

Never had the problem. Which bolt is it leaking out of?

Left side right behind the water hose. You can see the water seep out of the threads.

Was the rebuild after normal wear or after a meltdown?

Did you remove the studs?

Meltdown I suppose, the bike needed a complete rebuild.

I did remove the studs.

Could it be that your cylinder head is slightly warped?

Put your head on a piece of glass & check for flatness with a .002 feeler gauge.

That is on the agenda for today.

Checked head with feeler gauge, doesn't seem warped. Used some 220 grit sandpaper on some glass just to be sure.
