84 GL1200I. She sat in a trailer for past six years in Anza Borrego. Runs smooth around 3000 rpm and up in neutral. 36K total miles on this bike. Seems to be running lean. Backfires on deceleration. Starts up no problem. Really bad off idle performance. Sputters/misses. Poor power through broad range. Runs much better off idle under load or in neutral when choke open. Attachment is left forward plug. Looks pretty dry to me. Guys can you give me a short list of how to proceed please? Just checked the jpg and didn't really catch it that well but plug is clean, porcelain not colored at all but the tip is really white.

Could be in need of a carb cleaning or rebuild followed by synching the carbs.

The first thing I would try is a full can of Seafoam in the gas tank to see if that helps clean out the gunk from sitting.

You should also check to be sure no water or even worse rust has gotten into the fuel tank from the long lay up.

GoldWings like to be run. When they sit for long periods they begin to self destruct.

:D

Draining tank was one of the first things I did. I Seafoamed it today but only used per instructions. New fuel filter too. I was thinking about pulling the line off the tank and sticking it into a can of Seafoam. Any boneheads ever try this? I'm thinking cutoff valves too. It is running better little by little especially 85 mph down I15.:cooldevil: At least it ain't smoking anymore!

dirty intake valves can make it backfire and shudder try using some mmo marvel mystery

oil in the gas also the carbs are probably filthy. remember the fuel of today wasen't

what it was 30yrs ago when the bike was made.

Yeah the guy rolled it into a trailer and didn't even burn the fuel out of the carbs. Actually it runs pretty good considering it sat for six years. My blue 1200 sat longer before I got it and it just happens to have the same miles as the gray one and it fired up and ran/runs great. Although I wonder how good it could run with a carb sync.
