Hello everyone, this is my first post. I’ve been riding and working on motorcycles for a long time and now I have my first Goldwing. My sons father in law gave it to him. Been sitting in a garage for 6 years only 19,000 miles. Pulled the carbs, drained the gas, new gas lines, fuel filter, spark plugs, took carbs apart cleaned and new kits, set pilot screws at 1 1/2 turns out and new battery. Fired up after a few cranks, being careful not to fry the starter. Let it warm up took it for a ride a mile or so came back home. At idle it slowly slows down and quits even with the throttle stop screw all the way in. A Haynes manual came with the bike that has been very helpful. Tried to open the pilot screws and quickly figured out that I need to get a 90 degree tool to turn them. It ran good at higher rpm just slows down and dies at idle. Any suggestions while I wait for my tool to arrive?

Seems like the pilot jets didn't get cleaned out enough.

If you are new to Wings you might want to peruse this....

Lots of good info....

Welcome to the site! IT sounds like your idle jets are clogged. did you pull the jets? On the '81 carbs, they are pressed in jets. I use a sheet rock screw to get a bite. They do not come out easy. I had to soak a carb in Carb Chem to loosen it a bit and then work the jet side to side while pulling to get them out.

I didn’t remove them for that reason pressed in. I did clean them with cleaner small brush and air. I was wondering if the pilot screws needed to be turned out more? What kind of tool to you use to adjust them?

For the pilot air screws, first, the covers have to be removed. I was able to remove them by heating up slightly with a heat gun to loosen the glue. My initial adjustments were 1 1/4 turns while off the bike. After performing the idle drop procedures, ultimately, they ended up at 2 1/4 turns out. I had a small, 90 degree screw driver that could reach the screws while on the bike (real pain!).

Thanks, I think I’ll try the idle drop procedure before taking the carbs back out. By opening the pilot screws more shouldn’t it make idle faster?

The idle drop procedure will not make any difference if the idle jets are even remotely clogged. I know it is a pain, but you should pull those jets and clean them before attempting changing the pilot air screws and get disappointed. Also, there is a tiny hole in the carb barrel for the accelerator. It is worth check that it is also clean.

What’s the procedure for reinstalling those jets after cleaning?

The ones on my latest 84 were not completely blocked.
After putting A T F in the fuel, after using several tanks of gas.
Had to keep slowing the idle, as they were opening back up.
