Rubber to be removed for carburetor cleaning

[KEITH KRAUSE]

They sell entire carb banks for $100 at the only salvage yard we have out here, when they have a set. You should be able to find a carb body for less, but it might have to be on a bank of "parts carbs". A member here may be able to help you out if you place a request in the "parts wanted" section?
I just hope you get the correct carb. I don't have the factory manual for your 750. There MAY be certain jetting differences from the 1000 carbs. It's possible the 1000 carbs would also work, but the air jet (not removable) would have to be the same. The other jets you can remove and swap.
Which carb is it? 1 or 4? I doubt I have a spare, but I can look or ask a friend.

I was correct, it's the carb farthest from the choke. I don't know if that means 1 or 4. Sitting on the bike, it's the carb at the extreme right.

I have all the jets and everything. All the components looked brand new (especially the floats) when I opened up the float bowl. I had a hunch this bike was serviced just before I bought it. If only it weren't for that pilot screw tip that someone probably botched up and kept a secret.

Thanks for the offer, it's ok if nothing turns up. I've never seen a pick-and-pull around here in metropolitan NY, all the junkyards have become "used parts dealers". That first guy had no luck getting the tip out but we're trying someone else tomorrow.

Hi. No one I know has a spare for that type of carb body. I did drop by our only salvage yard. I work throughout the city, so I had a little time. They didn't have a parts carb, but they did have a complete bank. They marked it '78 GS750 and it looks correct to me. They wanted $125 . I took out the pilot screws on 1 and 4 and they were fine. I didn't inspect further. We both know you can find these carbs cheaper from other sources. I still think someone at this site can help if you ask.
"wiredgeorge" a member here, may be able to help you out. He works on carbs for a living. He sounds knowledgeable and would give you the RIGHT carb. I don't know if he'll sell you just a carb body. He repairs entire banks, etc. Bet he's worth a try. Give him a PM, it can't hurt to ask.
If you go with E-bay, ask questions! You may even try just living with it?You said the bike didn't run too bad before? You would run lean on the pilot circuit, but you may be able to install a larger 17.5 pilot jet and get close to a correct mixture? Just a thought.
I could always send you those salvage carbs I found, but I really think you can do better. With shipping, they would run you $140. Try 'george or the parts wanted here. Good luck and let me know what you find.

OK, thanks again Keith. I'd just have to live with less-than-satisfactory idling, that's all. If something happens I'll post to this thread again or PM you. I'll wait on the other shop to see if they're successful, if not then I'll get wiredgeorge's attention.

OK. Good luck. If you have any questions about re-assembly/synching/jetting, let me know.
PS: Don't forget to replace the manifold o-rings (unless they're fairly new). This should be done any time it's been "awhile" since the carbs were last serviced. They're cheap and if you try to replace the old ones you'll probably get intake leaks.
To help the new o-rings last longer, apply a coat of hi-temp' bearing grease to them. I also suggest getting rid of the stock manifold Phillips screws and replace with Allens. Torque the new o-rings to 6 ft/lb.
