GS650 starts but dumps fuel.

Believe it or not, these carbs are not totally shot. Both of those posts can be fixed and or carb bodies exchanged. Your hexagonal main jets are not meant to go in this carb body, you will need the round style like pictured. You already have a 122.5 main jet, this is considerably larger than stock, so it is possible someone has jetted these carbs for your setup.

My concern is what about the rest of the carb parts, which needle do you have in there? Are pilot jets stock? Hopefully, someone has taken time to correctly jet this to your bike setup.

My suggestion is fix/replace bad posts, clean existing components, note your specific parts on paper, correctly set your float levels, reassemble with new orings and see how it performs. With a big dose of luck, it may be spot on.

This is what carb #1 has in it:

Main Jet: 122.5
Air Jet: 150.0
Jet Needle: 5C45 (It has no grooves, and is not tapered)

I'll have to get the pilot jet when I get back to the house this evening.

This is all easy-peasy. There's nothing to these carbs. I was expecting something much more ominous.


:EDIT:
Pilot Jet is a 42.5

[Krunk_Kracker]

Pilot jet is 42.5.

Carb number one is cleaned, has new orings and painted up a bit.







One question though, I have a left over spring, lol. I have no idea where it came from, as I had everything in labeled correctly in zip lock bags. This was in my "Carb #1" bag...can someone tell me what this is so it can go be in it's home? I looked at all the schematics I have and it doesn't seem to have a place at all in the carb.

Goes with the mixture screw I think.

It's about an inch or so long.

Maybe I missed, but where does the enrichment spring go?

In this picture, the choke enrichment is the brass nut on upper left of carb. Unscrew and spring goes over protruding rod. Then reassemble. I assume that you have disassembled the choke and forgot to put it back in during reassembly.

DOH!! That is it, thank you so much!!

Either the o-ring kit didn't come with enough o-rings, or I'm using o-rings where I shouldn't. I'm two short for the fuel lines and vents.

OK - All the carbs are rebuilt, and getting ready to repair #1 since I cannot find a replacement carb body.


I just need to know what's a good baseline to set these carbs up at to at leat get it running? Like the air screw, etc?

[spadefoot]

I may have a carb body, if you don't want to take the repair route. When we were doing the rebuild on mine a couple of years back, I ended up buying I think 3 racks off ebay, all together. You're looking for the #1 body, correct? If I have one, I'll be happy to send it to you for the cost of shipping.

Yes! Please look at and let me know! That's the only thing keeping my bike off the road at the moment.

[spadefoot]

I'll be home around 6pm Eastern, will hunt through the drawer full of carb parts and see if I've got one in usable shape.

[Krunk_Kracker]

Thank yuo so much! I really appreciate it

[spadefoot]

I believe this is the one you're looking for. I took some pics from each side so you can make sure it matches your #1.
