This has happened to me twice in the last six months....
Whenever my G sits for more than a few days on the sidestand, one of the needle valves controlled by the float will rotate on the tang and get stuck. This creates a rich condition in that cylinder and the bike runs like shiite!!
It happened to me again this week. I had just installed some side-gapped plugs which made a noticeable difference. Then we had a few days of rain. I left the bike on the sidestand under the carport and when I went for a ride, after the rain stopped, it started spitting and sputtering. I isolated it to cylinder #4, the plug was wet after every ride, even after drying it with starting fluid. Thought it might be the wires and performed the 1/4" trim, and even switched the 1 and 4 wires to no avail.
Following my hunch, and instead of pulling the carbs again, I removed the float bowl to check (thanks Marty for the SS allen head bolts) and found that the wire gizmo on top of the needle had rotated and was jammed on the float tang.
I corrected it, put it back together and all was well again. And, I didn't even have to pull the carbs!! The last time this happened I isolated the issue to carb #2, and didn't have the allen head bolts, so I pulled the carbs, which I had just cleaned not too long ago and found this same situation. Once corrected, it ran fine. That time I made sure I installed the needles with the offset on the wires toward the back, closest to the float pivot point. Obviously that made no diffrence in this situation.
Anyway, thought this may help someone experiencing wet plugs for some unknown reason.
