XS 400 carb balancing

[pepperami]

My XS 400 runs well and has a good rev range, so that is good

I have found that if i use the side-stand that one of the carbs (Right) will drain a little making starting harder until it`s filled again when I put the bike upright.

That`s not a problem as I can use the center stand!

But no matter what I do to my bike, my idle is ALWAYS lumpy.

I have had them balanced , sonicly cleaned, new jets, diaphrams, ect, ect!

while looking at the mounts, I am thinking that the small brass tubes that are blocked off on mine should maybe be linked?? by a small length of rubber tube??

Any advise is greatfully recieved........ thyank you

one brass tube goes to the vacuum diaphram on the fuel tap.

the other has a cap.

lumpy idle is due to the pilot system mix out. need to tweek the screws to get best idle. if not sure how to do, get back on here.
