CB500/550 / Re: Plugs fouling at idle
« Last post by davidcumbria on Today at 06:28:43 AM »Interesting thread. This fouling at idle - is this when the revs drop after running steadily for 20 seconds and can be cleared by revving the throttle to restablish the steady idle? Mine does have that tendency on the denso plugs but also one cylinder which is cooler than the others so I’m guessing that’s the one that fouls.
I have found on many different bikes cars lawnmowers-that iridium plugs give better starting, smoother idle and avoid fouling on two strokes. It seems there isn’t one available for the 550 - why not ?
