1983 GS 1100ED backfires?

[Anonymous]

After cleaning the K&N airfilters and reoiling them (properly), after replacing the plugs with new (proper gap) I find that the #3 cylinder spark plug is sooty and that the bike backfires when I come off the throttle. Any suggestions?

I think you damaged the boot changing the plugs and your dumping gas into the exhaust pipe that is unburnt.

You may have over oiled the K&N pod filter on the #3 carb and as a result it is getting less air and is running rich. Try drying the filter gauze element and blow compressed air through the filter to get rid of the excess filter oil. I doubt that you could damage anything in the crab just by oiling the filters.

Thanks for the help!! I'm uncertain how the spark plug boot is attached to the high tension wire. Do I just pull the boot off? Is it a friction fit? GusDearolph

Hold the wire, twist the boot off counter-clockwise. General replacements can be had at most bike stops and, of course, the local stealership

I had more or less the same problem after over oiling my air filter, but on all 4 plugs.
