Hey Dennis...I took everything off of the top of the engine that I could
without removing the whole top end so far. I have found nothing yet so I'll
keep you informed. I'm trying to eat enough bologna to keep me going until I
get it all apart.
I was able to save the cam cover gasket. When I replaced the cam cover gasket
last year I put High-Tac on the bottom side of the gasket and silicone ("snot")
on the top side. Bob recommended this and now I know why. I took a razor knife
gently around the gasket on the top side so that the gasket stayed stuck to the
engine itself. The High-Tac glued the gasket firmly to the engine and the
silicone released it from the top side. I will post some pictures of the
disassembly later.
I wrapped the cams in saran wrap and marked each one. I have some more tips
that I will share with the group later that work well. HotrodMamma.

I'll let you know. I do have a parts bike with a good top end. I was weighing
the idea of just swapping the whole top end. If nothing I do have parts but I
hate to take that cam cover off. I'll have to try and save it if I can.

Let me know what you find. A broken valve spring would be a first for
me. Other than the faulty hydraulic adjuster problem, I've never seen a
cylinder head failure of any sort. If it didn't drop a cylinder at time of
noise, I'd bet on a cam follower. Sure be easier to repair than a valve. Good
luck.

I went for a ride on my '83 650 Nighthawk today. It was about
170 miles round trip. Coming back home I heard a noise in my top end. Lucky me,
I was at a town only 20 miles from home. It was a tap, tap, tap. I put some oil
in even though I put some oil in before I left home as it was a bit low still.
I rode it slow for about a block. There was no noise until I put it under
load...tap, tap, tap but not real loud. And then...PING! ping ping ping. I
think I broke a valve spring. I pulled it over. I was riding with Bob so I
jumped on the back of his bike (ARRGGG! I hate the back seat!) and we came back
and got the trailer. I am pulling the cam cover off tomorrow to have a
look-see. Now I have 3 bikes and nothing to ride! My old Harley needs a clutch
and I'm waiting for the clutch lever that was donated to me by a very nice
member of this forum. ;) for the Nighthawk Nightmare project. Between the
generous donation of a tank and that clutch lever from members of this forum I
should at least have one bike to ride again soon! Thanks to the generous
members of this forum for helping me to get a bike on the road again.
