Poor man's carb adjustment

Postby aznyaz » Fri Jan 04, 2013 12:22 pm



I recently discovered webbikeworld.com and read this article and was wondering if anyone has tried this on Goldwings or is it something to be avoided. I believe I need my carbs rebuilt because of a midrange sputter caused by my #2 carb not idling and probably insufficient fuel delivery in that carb. I only have 17,500+ miles on the bike (it had just over 13,000 when I got it) but it had sat for quite sometime with little use. I have run several cans of Seafoam through full tanks of gas but am curious about this method.

The cleaning method would help if in fact there is a problem in the fuel passages.
However.....on the 3 gl1100's i've run,I always find that the slides are sticky.
Midrange sputter is associated with the metering of the main jet by the slide needle .
Or if the cylinder will not fire at a idle either,the slow speed jet is plugged.
It's a bit time consuming,but I do suggest hand cleaning the carbs,getting the slides to move butter smooth and then a real good sync.
Even the sync can be done on the cheep.I made my own "gauges".My gl1100 would pull smooth from idle to red line scary fast.

Take note that before i put them back on the bike,I used a shop vac attached to each carb,one at a time,operated the throttle and verified that each slide operated the same.

Thanks for the quick response. I am not ready to tackle the carb rebuild on my own just yet, that's why this seemed feasible. Probably too good to be true. I do have a place to take/send them to when I'm ready ($$$) to do so. They use the Randaak's rebuild kits and do some extra tweaking for what seems to be a reasonable price.

Back to the original questions; is this a feasible method or could it be harmful the carb's internals?

It won't hurt.Obviously you don't drive it during this process.
It may help "clean up" the jets but unlikely will clear one that is plugged.
It's worth the $10 to try tho.Not much time or money to invest. ;)
Who knows....maybe the mechanic elves will sprinkle some pixi dust in the intake and it will be OK. :D

That's what I'm hoping for. One last ditch effort before I yank them off and spend the big bucks!

I've "rebuilt"/restored many sets of carbs.So far all the innards were good so the only"kit" I had to buy was a set of bowl gaskets for a few, but only after I bench filled the carb with gas.
Jets just don't wear out,they plug up,a cleanable solution.
On one 70's carb I did have to replace the needle valve and float.
It really is a DIY job.tedious and detailed.

I use this method all the time as the first step in carb rebuild or not..I use 50/50 sea foam/gas or stronger let it sit in the carbs over night or longer..then hook the line back up and run her..smokes a lot while burning off sea foam mix..sometimes it works sometimes not...
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

Don't be afraid of those carbs! Once you get the hang of them they're not bad at all! I'm looking for a Goldwing now because mine got burned up in the fire. I would actually prefer to get one with carb issues because I know that's something I can fix and I should be able to get the bike cheap!
