put fresh plugs in, after chasign the threads on the plug holes. torque em down properly, then run it good for about 30-45 minutes pull em and look down on them.
see attached pic.
the area circled in red will tell you if your rich or lean and should be a slight carmel almost burnt toffee color. the area in yellow will denote heat range of plug and should show a change in color from heat about half way up from the base. this plug was fouled during a carb icing incident in december

Yesterday I ordered some new plugs from NGK both standard & iridium. I bought the bike used with 19,000 miles on it and have put 4,000 miles on it since. Had a 20k service 3 months ago, but those plugs look way older than 3 months/3,000 miles . Thanks for the suggestions I will post up the results
