Thanks for the help. I did check the website for Champion.
also could use N 12 YC. Plugs look to be oil fouled. Just bought
this bike with 40,000 miles. so thinking this fall will pull heads and
cylinders to look...see. will plan on valve guides, valves, seals,
maybe springs too and valve job. would like to go .30 over on piston
and new rings. Will do the work myself.
