carb help GL1100

Postby Iggys » Fri Feb 01, 2013 7:00 pm



Someone please help me. I now am suffering a carb issue. Bike ran fine but had been re-jetted by the PO in Salt Lake City. Me and the bike are residing in Los Angeles, so I acquired a set of good used stock 145 jets and carefully swapped out the 140's. Don't want to run lean in LA. I removed the air domes/piston/spring and gasket from #1 and #3 carbs, labeled each. Slide the carbs out the left (phew, was that tedious!) flipped over and swapped the jets. No problems. Also checked the idle jets and all matching #35. Back in, domes back on, o-rings confirmed under intake tubes, and ta-da, bike will not run. Very choppy at rpm, hard to start, slight puff out a carbs every so often. It will idle but will die on twist of throttle. Full choke will cause the bike to rev up though. Ideas ? Did I miss something ? Sprayed carb cleaner all around at idle, no indication of vacuum leaks. No black smoke or any smoke for that matter. 28,000 on clock.
Thanks,
Iggy "sad and depressed" Scarpitti

It's possible you may have to change the needles in the slides as well. Were the jet holders clean? When you flipped the carbs over,you may have gotten dirt in the jet holders and /or the idle jets.

Did you reset the floats? That is very important. They have to be at 15.5 mm and you set them with the carbs on their side. I would see if all the exhaust pipes heat up evenly and in about the same time. You may not be getting gas in one or more cylinders. Pulling the carbs the second time is easier.

Thanks, I plan on doing that as well as replacing the cooling pipe o-rings ( not related to carb issue) as one leaked a bit whilst wrestling with the carb body.

Welcome to the world of 'Wings~ :D
8-) You will learn how to get those carbs in and out of there in, oh... :roll: I'd say (help me here guys. What'd 'ya think? About 20min.?) :o

If not this next time, then pretty soon you're going to want to install a 'zipper' to facilitate more rapid access...

(You say you can't find one listed? :shock: )

http://www.randakksblog.com/

This guy seems to have changed his website more along the lines of actually trying to get somebody to buy something- he's a wealth of knowledge on these things- used to be an easier to use layout- oops

But next time you have 'em out make sure the slides are free, and that the floats all operate freely too- you might make sure each carb is getting fuel, and that you haven't accidentally crossed over any of the plug wires- long of the short of it is don't be intimidated by the task at hand- allow yourself ample time and take your time- the first few times you are probably to become overwhelmed by it, but keep a cool head, pay close attention to detail- there are lots of very helpful resources- this being my favorite one you've found- heck man, there's a factory manual right here you can download and even print pages if you need to (I know I sure have on more than one occasion!)

I'm mostly trying to give you a pep talk than anything else, but you can get it- just keep at it, don't destroy anything (take it slow) and if you don't 'get' something, ask. We're - somebody is here - to help you out. :idea:

Figure out how to search these forums and you'll find just about anything you're looking to fix, if not, ask and me or somebody will help you fing 8-)

Thanks for that. This forum has already helped me fix my slow battery killing starter (no $$), made it a breeze to replace front bushings/seals and upgrade to affordable progressive front , rear shocks and or springs. I now have my own wooden fork spring removal tool ha ha ah. Was feeling really good with myself till this. Will take it slow, methodical, and with patience. I'm pretty good with wrenchin' on our Moto Guzzis ( '72 police eldorados) and the carbs on those are so simple and so easy to understand in their circuits. Goldwings are a giant leap ahead.
Thanks again to all,
Iggy

Still thinking about that zipper concept though....

Right on~! Yeah, mostly a figure of speech (the zipper), but I'm sure you'll do better next time understanding the intricacies of these Kei~Hin jobbers- really quite marvelous machines once you have become familiar, as some seem to have (I don't profess to, just a lot of experience.) 8-)

Well I did it. Pulled the carbs out AGAIN and found one float was way way off. No gas getting to carb 3. Made a little "L" out of floor tile as my gauge and reset them all to spec as shown in this forum. Also made the little "T" handles for the idle needles. Set all the jets to 2.75 out. Bike is slow to warm up but pulls great at 70mph+. Need to focus on idle circuit next and fine tune. Maybe build the four gauge vacuum meter.
Thanks all.

Yeah, it can be a lot of fun geting all the holes through the slow and idle circuits clear. Guitar strings and spray B-12 got most of mine acting right, but there are still a few glitchez - sounds like you've made tremendous progress- keep it up and happy sailing- sounds like you should be cruisin smooth come this summer, best of luck to you! 8-)
