For the odd shaped gasket/o-ring sealing the jet cover, part number is
92055-1290 -or- 92055B
Available from Partzilla for ~$9/ea + shipping
definitely an expensive part for an o-ring, but worth it IMHO

With o-ring cord, you can make your own. There's even a kit with assorted sizes and a jig to help make a good square cut and hold the ends for applying the super glue. Or as mentioned, just cut an o-ring and spot glue it to the odd shape.

Meant to mention this and forgot....
If it's leaking between the carbs, that's the float chamber, and the carbs have to come off and be separated. That's where the round o-ring is.
The jets are in the bowl section pictured below and have the o-ring in this shape at the bottom of the carb. This can be removed with the carbs on the bike, with some effort. The gasket embeds in the bowl/cover.

I just rebuilt both carbs. The float valve is held to the float with a small clip. The float is held into the bowl with a small pin. Nothing will fall out. I pulled the entire assembly and then pulled them apart on a bench, but I don't imagine it being very easy to get in there and replace an o-ring between the cylinders.
The seal is a plain old o-ring. 54mm ID x 2mm thick x 58mm OD. There are some buna-n 70D ones on McMaster. part# 9262K533, $16 for a pack of 25. Better than the $10/ea from most places, and you'll have spares to clutter up your toolbox.

So essentially, it is very possible to replace the bowl gasket without removing the carbs? And nothing will fall out that I'll have to pop back in place, correct?
Guess I'll have to order the gasket next time I stop by the bike shop.

People have changed jets with the carbs installed, some switch the screws for hex heads to make that easier. Just have to be careful about stripping the phillips heads getting them loose. Seems more tedious than carb r&r if you are earshaved.
I've always advised against using any sealer on carbs. If it squeezes out, it migrates into the passages and won't always clean out. It's also a nightmare on automatic transmission pans when the happens. Sealer can be applied sparingly, but I always avoid it on carbs. However, it looked like there was sealer used on my carbs previously, not silicone, but something like Indian Head shellac that sets hard, maybe Yamabond, not sure. I reused my gaskets and just flaked off the sealer.

Leaking carb bowl
Well, with spring approaching I've decided to get my Vulcan ready. While trying to start it, I've noticed the right side carburetor bowl is leaking a decent amount of gasoline. So I'm wondering, on the 750's, would I be able to just remove the bowl on the bike to reseal, or does the entire carb have to come off?
