So ...need a bit of direction-was carbs, not coil pick up

The replacement long brass fuel T's should be the same for both early and late type carbs, the short ones are for the upper vents on the early type carbs only. Larry is correct.

But it was in 2014…

Umm...That's around the time the ole XS11.com became inaccessable to me. (￣ー￣)

Back to da matter at hand? (O_o)

I HAD to have/buy the SHORTER (VENT) Tees frum Sirius Consoliderated cuz of the way things were/are on my "earlier" carbs. (ﾟｰﾟ)

IIRC they was sort'a PRICEY but I wuz glad S O M E O N E had wut I needed. (•‿•)

However, I bought and used the LONG Tees fOaR FUEL from HERE-

Thank you Bikerphil and Larrym! Ok I’ll get those Tees ordered. I have an uncle living in Wisconsin who is coming for a visit, feels like most of his luggage will be spare parts for my bike 🥴.

One thing I don't recall being mentioned was the condition of the rubber coated fuel T's between carbs 1+2 and 3+4, it should be visible from the outside/between the carbs if leaking.

Another thing is maybe remove the carbs, take the air box out and set aside, then reinstall the carbs, then you can pinpoint which carb(s) is leaking.

Yeah, that's one of my next to-dos.
QUESTION: Is there supposed to be enough vacuum to make a high pitched squeal at the gas cap? It stopped whe nI popped the cap-obviously.
And when I turned the petcocks back to run, from off, there was discernible bubbling in the tank. Never noticed before.
Of course these are new hearing aides and maybe I just never heard it before. Wondering if vacuum is sucking out gas even when the bike is off.

[bikerphil]

Jonny, you might as well clean the vent in the cap, it comes apart fairly easily. If it's blocked, the carbs will starve for fuel. I would remove the entire cap from the tank first, it is held on by just one screw.

And the sound you are hearing lets me know that the vent IS a problem. You are not getting a steady supply of fuel. and the bike will not run correctly until the vent is working properly again. It could be that was the biggest problem all along!
