1st Valve adjustment was a success!

... and it was easy too. Intakes were fine, Exhaust valves were too tight. Now my bike idles perfectly, I used to have to keep the choke on for at least a minute after starting so the engine wouldn't die, now the choke can be turned off after 20 seconds, even in chilly weather.

BTW, I pointed a flashlight in the spark plug hole just out of curiosity, and the top of my piston, was completly covered in black, carbon deposits I suppose (my spark plug was a light tan though). Is this normal? I didn't expect a pristine glimmering piston, but a didn't expect a pitch black one either. It's a 4000mi bike BTW.
