vacuum leak - carb boot replacement

My 1979 GS750 has not been running well. It stalls and seems to be running too rich.

I used quick start on the carb boots to check any leaks and sure enough, the RPMs drop considerably when I sprayed two of the boots on the cylinder side of the carb. So I have a couple leaky carb boots.

I can't find those boots in any part manuals for the life of me, and the Suzuki dealership in my neighbourhood has not been any help whatsoever. I can find plenty of carb boots for the air box side of the carb, but not for the engine side.
Why can't I find this part anywhere? Are the boots the same on both ends of the carb?

I'm also wondering if there is a way to temporarily fix leaky seals around the carbs.

Thanks!!
 
Yes I have. And I can only find the boot for the airbox side of the carb.

Thoughts?
 
I believe he is looking for the intake pipes that bolt to the head, not the boots that run from the air box to the carbs.
I do not see them listed on those part diagrams, but the ones I need were listed on the head assembly diagram as #25 PIPE, INTAKE RH 13110-45100 and #26 PIPE, INTAKE LH13120-45100. however I have an 80 gs850glt.
Note please do not think that these are the ones that will work for you.

Better look again -part #16 pipe and #17 -O ring
 
Eric gave you the links in post #4 and even gave you the item number on the fiche.

If your bike has sync ports on the intake tubes, you might want to stick with Suzuki tubes, not the ones from JBM.
I don't see ports on any of their tubes. And the cost is not all that much greater, but certainly worth it to have those ports.

Yup, rebuild it with new o-rings from cycleorings.com, and probably some new fuel bowl gaskets.
