i had my bike apart yesterday doing some pre-maintainance.
last years plug was barely discolered, and brown discoloration, only on half. no black..
there was also a tiny bit of white crusty looking stuff on the ground electrode but overall scarily clean!?! i run a rich mix, and i expected some more crud, but the plug looked like i only ran it for a few minutes. my cam wont take clear close ups sorry no pics
does anyone have a source for 2 stroke plug fouling chart? ive seen them for cars, has pics and descriptions.
