Before you started to take it down, did you turn the motor over and watch for unusual things happening ? I would have expected to hear or see something. I'd hate for you to have to do more than what is needed.

To: [email protected] Date: Thursday, July 30, 2009, 4:23 PM 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.

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. --- On Wed, 7/29/09, Creative Residential Designs <[email protected]> wrote: From: Creative Residential Designs <[email protected]> Subject: [Nighthawk Lovers] Broken valve spring... To: [email protected] Date: Wednesday, July 29, 2009, 11:58 PM 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.
