Fouling spark plug

Postby montgomery63 » Tue Aug 30, 2011 1:13 am



I have an 82 GL 1100 (naked wing) with 70K miles. It runs well. I just got back last month from a 1250 mile ride and it ran great the whole time. Recently, when I went out for an evening ride with my daughter as a passenger, I noticed a lack of power and the engine sounded different when I applied the gas. Upon return, I checked the spark plugs and the right front cylinder spark plug was fouled...Sooty black, not oily black. Dry black. I changed the plugs and it ran fine for about a hundred miles. Then the same thing happened. Lack of power. Obviously only running on 3 cylinders. Checked the plugs again and the same plug was fouled. The other plugs look fine. Any ideas of what to check first? I know it could be something serious, but am obviously hoping that there might be a simple explanation thats easy to fix. Any chance it could be a carb adjustment? Any advice is appreciated. I should add that the exhaust runs clear - no white smoke when it is running. Thanks.

Thanks for the input. Interesting you should mention sea foam. I have been running it with almost every tank of gas this year. Just stopped using it for the past month or so, about when the problem started. Maybe I do need to just keep using it. I will try that. Thanks again.

If you have been running it regular like that then I'd pull the carbs for a closer inspection, but that's something I would do... You should do as you wish...
