Recap: installed TT fly wheel and set the valves to the middle range of the stock specs. As I have the RHC cams Eddie suggested I tighten the clearances and the cams quieted down a bit. Take it out for a shake down ride, get about a mile from my house and life turns bad. Cruising in 4th gear and all of a sudden there is a CLUNK from the engine and the engine dies. Get my buddy to rescue me in my pickup and the bike is now in my garage. Got around to opening up the engine this morning and my problems appear to be as follows. The right exhaust bucket appears to be much lower in the head than the other three valves. When I rotate the engine manually there is a grinding noise (which appears to be more from the bottom end) and I eventually get to a point where the engine does not want to turn any further. Have I dropped a valve? I assume at this point I am going to have to take off the head and determine what's what. Is there some logic to disassembling the engine when it is not at TDC? Right now the cams are both pointing up and are not in contact with the valves so removing the cams shouldn't be too hard. Do I index every thing as usual and just make sure to reinstall the cams as they are? I assume that if I have to take off the cylinder it won't really matter where every thing is as there will be enough stuff broken that I will have to start from the bottom end and line every thing up. Let me know what the best way is to proceed from here. Thanks for the help in advance!
