Issues while breaking down the GS1100EZ Carbs

[chef1366]

There is crud built up in the port that leads to the idle mixture screw. Either cut the part off where the threads end or clean it with a drill bit but don't damage the threads. I cut the thing off with a dremmel since it's only there to cap off the screws.

I also have a dremmel on my work truck so if all else fails I'll start cutting.

Well I had some luck today! I got them all out except the one that I already boogered up.

I was able to get the screws to turn in after soaking 2 nights w/ pb blaster in the holes. I then used one of my copper bore brushes (for gun barrel cleaning) to clean the hole as best as I could. I frequently washed the hole w/ wd40 sprays. Then I backed the screw out to its "stopping" point, and then I just screwed in, out, in, out, in, out, ect.... Just bumping the stopping point each time. Stopping every 30 seconds or so the rinse the hole w/ wd40 again. Everytime I bumped the spot the screw came out little by little.

You basically just have to work the crud out. Now the last one is gonna be a bear because I already stripped the head out. My buddy, who has access to a robotic machine shop, is going to look at the last carb this weekend.

Hope this helps someone some day.

Broke down carb #2 tonight. The needle jet holes closest to the bottom where plugged up w/ gunk! There couldnt be much fuel flowing until at least half throttle. In the dip it goes...

Nice work getting the pilot screws out.

BTW, same routine is needed for removing header bolts. Lots of people snap them off due to too much force. PB Blaster, heat, work back and forth...and they will eventually come out. Wish more people would follow the technique instead of learning the hard way.

Good luck

Well unfortunately I learned the hard way on my first carb haha! I'm not a gs carb newbie either.

I rebuilt my 750 carbs last spring, the air screws were the only thing that was easy about those!

To be safe, it's always better to go on the richer side, so go with the bigger ones.

I'll ask here. I have a 1982 GS1100EZ with stock exhaust and a Uni foam filter. I'm rebuilding the carburetors.

I bought 4 K&L rebuild kits for the "80-83 GS1100E" from "Z1". The kits come with 2 main jets. a 107.5 and a 115. The stock jets are 110 which is what the manual says is correct.

Question: Which one of the new jets should I use to replace the 110s. The 107.5 or the 115? Or should I try to find some 110s? I'm leaning towards the 115 but I thought I'd seek advice.

Thanks

Reuse the stock jets. And check the rebuild tutorial linked in my signature for info on some things to look out for when rebuilding.

I have your guide by my side. Thanks.
