Ok, time for an update, I guess. I got the valve switched out, bought a gasket kit from partsnmore.net, installed that head and went about putting it all back together. I soon found another problem. It seems that I got the cam timing off to the back head when I put the crank in it last summer. No big deal.....yet. I decided I had better look at the valve tips on that head, since I had to do work back there anyway, with the cam timing. Well, 3 or 4 of the exhaust valves are "not looking so good", for the technical terminology. I had to pull the engine off the bike to pull that head, and that's where it sits now. Engine on the floor, rear head off of it. In the late 80's, Hon-duh had a service bulletin on this issue of the valve tips pitting, mushrooming, etc. If the valve tips weren't mushroomed, or have pieces protruding, they would install "caps", which I'm guessing was to make a fresh hard surface at the tip of the valve, along with a different adjuster, which I'm sure would be shorter to make up for the cap. I'm tempted to try and find some of these kits, as none of the valves are going to be in great condition. Otherwise I need to just swap out more valves out of the parts engine, slap it back together, and be conservative with how high I let it rev. Aftermarket parts are pretty much non-existant, due to that bike only being made for 3 years. Any other ideas?
