950 slight running issue

So I'm having some issues with more than usual backfire on decel on one cylinder, slight rough acceleration and running at lower RPM, and a RPM gauge that's not operating smoothly/steady while cruising along on asphalt

Since it seemed to occure and progress after I disassembled many parts of the bike to replace the oil pressure sending unit, it would seem that I either didn't properly seal/seat/or attach something with/in the air box of OR I screwed up the synching of the carbs. I'd like to think I was thorough with the reassembly of the air box and I just ended up screwing up the synching of the carbs by all the moving and twisting I did with them...

The thing starts up with no issues... As a little tidbit of info...

Does all this sound reasonable OR do I have some other issue occuring?

You just need to go through everything again if it's just happened after that work. Is the fuel fully turned on? Stick coils fully pushed down? Choke cable fully home and not snagged? Goes for all cables/breathers. Carbs fully home in the rubber manifolds and ditto to intakes. Vacuum pipes fitted/blocked.

A rough check on the sync is just look into the carbs as you blip the throttle. Slides should rise together. (More to it than that of course).

Re Balance the Carbs.

Thought mine was way out of whack and needed Valves adjusting.. Ie Never have adjusted them.

Even bump the rear cylinder up a tad when balancing. Raise the idle a little bit and you will be surprised.

PS mines got 130K on in and never been touched.

Well I'm staying optimistic that's the issue
I'm headed back across the U.S., I'm going to try to find a shop along the way that can schedule me in for the carb synch...

I leave Monday from Massachusetts and there seems to be a good shop in Akron Ohio I'm hoping they can squeeze me in Tuesday, otherwise It could be awhile until the next good shop (Denver?)...
