Re: ques about plug chop
some carb cleaner and a wire brush is a good way to clean the plug, and as kCvale said, make sure you are using the correct plug and a good quality one.
I tune all my engines to run a light chocolate brown color plug, the type of oil you use and the amount in the mix will also have an efect on the plug color, main thing is you dont want an engine running in a way that is so lean that you end up with a white or very light gray color plug.
If you're running Opti2 or another high grade synthetic oil at 100:1 ratio, then a medium to dark gray to light brown may be expected, but running conventional oil the plug color should be brown in my experience.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
