Both problems fixed now. One question i have though - the line from carb #2 to carb #3 was a straight shot. The line from #1 to #4 has a junction in the middle, splitting off to a hose that leads nowhere and wasn't capped. Should I cap this, replace the line with one that goes directly from #1 to #4, or leave it alone? Thanks for the help!
If it's a vent line for the float bowls, don't cap it, as it's supposed to exit to open air.
Good Fortune!

They're not coming from the bowls, though.
Doesn't look like my photo came through on the original post.

If the hoses in question aren't from the float bowl vents, there should be other hoses that do connect to float bowl vents or at least other open float bowl vent nipples that have no hoses connected to them.

I found out by accident, that if the bowl vent gets into moving air at high speed, it can really lean out a mixture... very bad at high speed / high load. I verified it on a wide-band o2 analyzer, and could repeat it by moving the vent tube to specific areas.
EDIT: looking back, it appears your capped tee is for the emissions valves, which are probably removed. Leave it capped.
Bowl vents will be anywhere above the bowls.
You can get the various manuals for that specific bike by following the links in my signature.
Yours looks to be an 83 Kz550 H2 Gpz. IT will be covered in the appendices of the factory manuals I have posted.
Also, it would help to put your bike in the signature so you don't have to keep posting what it is.
