GS850 Carb help

[Roadflare]

i have this 1980 gs850 i rescued, and its been running rough, it just doesn't sound good on the left side of the motor. The exhaust sounds really muddy is the best way i can describe it. so i dove into the carbs this afternoon. the diaphragms in 3/4 are good, one doesn't raise all of the way but still forms a vacuum. Everything is so rusted shut on the top end and the bottom that i was only able to get into one of the dang carbs to degunk. after about 2 hours worth of swearing i have given up, because i don't want to strip the screws. my question is would it be better to just get new carbs if they have been neglected so hard?

It was stock when i got it ($free.95) and i did alot of mods to it, frame, paint, bars, etc. because it ran OK-ish.. and was fun to bomb around on.
but now i am getting into the important stuff.

On the new carb topic, i haven't been able to locate any BS32ss carbs for sale, I LOOKED! haha. what other carb set up would work for this killer bike? if i could get it running right it would be a screamer!

Full motor tear down is slated for this winter.

That thing is killer brother! Love it! Dirty. I think with some patience you should be able to find a carb set on ebay or look if someone on here if selling a full set. I just found a full set for $100 on ebay. You could even try looking for some local salvage yards even Craigslist. Guys sell their bikes for $400 for parts. If you could dip them as is you should be able to get them loose. Have you tried that?

I also just looked on ebay and found a decent set in bidding right now. Type in "Suzuki gs carb". You'll find something brother.

My question would be: if the left side of the engine sounds "muddy", why are you reporting on the condition of carbs 3&4?

Carb #1 is on the left, under your clutch hand, carb #4 is on the right, under your throttle hand.

Clean the carbs!!

Do you have an impact driver? These make short work of stubborn screws:



A word of caution, though: You have to be really careful dealing with delicate objects made out of soft metal. Like carburetors. I had to use my impact driver to ungang the carbs from the brackets holding them together. (I don't think I used it on the diaphragm caps or float bowls.) And I had someone help me by holding the carbs steady while I whacked on them. And I had a folded up towel underneath to absorb some of the shock.

Worse case: the diaphragm caps and float bowl screws can be drilled out easily. Use left-hand drill bits, not any kind special screw extractor device. Then go to the hardware store for replacement (stainless steel) screws. I recommend the stainless steel allen head variety, if you can find them.
