Wet spark plug

There's gas involved so I'm assuming carb. 94 that's had the goat chopped out, baffles punched. By previous owner. I coastered the bike. Changing plugs today I notice the right rear plug is wet. Good color but a bit wet. None of the others are wet tho. Runs great. Only issue is the popping on decel, but only from the right side. Don't think it was ever rejetted since it doesn't seem like it's ever been apart. Ideas?

Shouldn't really need jetted with a de-goat, it you change the filters to pods then you should. Did you pull the plug and check spark against the engine casing? The popping from the right exhaust shouldn't have anything to do with the rear plug. You might want to adjust the fuel/air screw 1/4 turn at a time for the front carb to see if that helps. You'll probably have to turn it in and count each turn to see where you started. Usually 2-1/2 turns out is a good start.

wasn't looking to re-jet just giving what background I do know of the bike. did check for spark. something else I just thought of, the vacuum line from the carb to petcock was off when I took the bike home. could faulty petcock have something to do here? may try air fuel tonight if I have time if only to be sure it is right.
