I know this is an older thread/conversation... but does anyone have the source or part numbers for a 500 head, Thermostat, water pump, and the Yamaha gasket yall talked about? I have the same machine, exact same symptoms, and need to do the same repair. Bought it second hand. It anyone has the carb replacement source and part, that would be great as well. Thanks in advance for all of your insight and advice shared. It helped a bunch.
