98 GL1500 carb pilot screw

Post by Jag39 » Thu Feb 07, 2019 6:56 am



Quick question. I am in the middle of rebuilding my 98 GL1500SE carbs, and ran into something interesting on both pilot screws. Both were screwed in tightly, neither had springs or washers on them. In other words, they were totally shut off. Bike has been running great for the 2 years I have had it. Tore the carbs down because the left one suddenly started dumping huge amounts of fuel onto the ground at start up. Did they change something on the 98's that required totally shutting down the pilot screws? I don't understand how it would run with these shut off completely, but it has, and flawlessly, until the recent problem. Suspect if I decided to get new pilot screws, the seats would be wrecked, anyway. Another thing. The pilot screws don't look like the ones I see advertised. They are cone shaped on the end, and have some other material on the tips.

I'll bet 10 cents that what you see is the carb drain screws.Not the idle jet screws.

Alright then, that makes sense, and I feel like a total idiot. Done many auto carbs, some single motorcycle carbs, first time jumping on these Goldwing carbs, and hoping that it actually runs again when I am finished. I appreciate it guys. Have to say, it had me stumped. Which also means, I haven't found the pilot screws yet.

The drain screws are attached to the bowl..The idle screws are attached to the carb body.They may not look the same.There may be a restrictor cap or a cover on them.Can't seem to find a quick picture but Google images should reveal what your looking for.

When you identify them take a picture and post it.
I'm sure your not the only one looking.
Keep us posted.

This is a picture I found of the pilot jet screws with arrows pointing to them. You can see the carb bowl drain screws in the picture also.

Also those screws are usually covered with a cap of some kind and are shaped in a D shape and you will need a special tool to adjust them. You can get around that by cutting a slot in the head of the screw to fit a regular slotted screwdriver.

IF you do pull the pilot screws out, be sure to screw them in and count the turns for each one before pulling them. Seat them lightly so they don’t get damaged.
I replaced mine with new ones and cut a slot in them with a Dremel. I use a long screwdriver with a spring shank and a small flat head bit to adjust them. It’s hard to get the “D” head on them to adjust them because they are recessed in the carb.
It takes some patience to get to them while running, but it can be done.

Wow, thanks for all the info, guys. Yep, completely missed those screws, since they were covered up. Just went around the carb looking for screw heads. All the info was a big help, and the photo really zeroed me in on them. Thanks all!!
