    Its not a real clear shot of the plugs, but are they maybe water damaged?
    Have you ingested water at all? Are you losing any coolant?
    How long are the plugs lasting and how many times has it happened?

    Can't see the plugs well either. Are they white, wet, brown, black?

    I'm wondering if the charger is slipping. It might just be that the clutch gets a chance to cool down while you do the plug change so it only APPEARS that the plugs are the issue.

    Seems like there has been a run lately of people needing to monitor AFR's.

    The only way to know what your rrfpr should be set at is to monitor your afr's.

    Sigh, it's like the same question with a different story. Pick up an AFR reader and that is the only way you will be able to know for a fact. Those plugs don't tell me anything because if you wheren't full throttle and shut off the engine and then checked and took a picture and just let it idle like most people would do then you will get a false reading.

    In my opinion, I think you are running too rich at the Fuel Pressure, whch might be why you are fouling plugs soo often. But then again, it's just a guess until you get an Oxygen reader in there.

    No way in hell you are fouling a plug. Its heat related for sure. My guess would be air in the IC or as stated a charger clutch slipping. Change your oil, could be gettin thin from heat.

    I haven`t ridden mine in 2 years. It kept overheating at wot and was getting worse. Now I need a new seat cover and another new battery. What is an `05 RXP going for with less than 60 on the clock? Whole bunch of mods.
