1981 KZ1000 suggestions

I've been scrolling through this group for the last half hour without any luck, time to start a new thread... I have stock carbs, a set of 4-to-2 pipes, and both pods and the stock airbox available. Of course everything I've read suggests that the pods are a royal pain, so I'll stick with the airbox for simplicity. I also have chains with two different sets of gears, and no clue how to decide which would be better suited for me (I've never ridden the bike, it was trashed when I got it, so no experience on how it started out).

So with a fairly stock starting point and a limited budget, what do you guys suggest for upgrades or mods to the carbs? They are mostly disassembled at this point, getting prepped for paint. It appears that PO installed new gaskets and floats, but I'll be checking to make sure they are set right. Otherwise the insides are very clean for something this old. Are the stock jets a good choice? Should I be looking for any other problems?

What about home-grown mods? Is it practical to try and polish the bores with a dremmel? Anything else I could do that might help out?

This is just a wild shot in the dark, but I'm not finding any discussions about problems/solutions for factory stock issues... either because there aren't any worth mentioning or because those discussions are buried too deep in the forum, but since everything is being torn apart, I thought it couldn't hurt to ask.

with your 4into2 exhaust stock jets are probably close enough to start with.after you have it running you can do a plug check and decide if you need to change the jetting.

wasting your time to try and polish the inside of the carb throats.

It seems there are differences between the J and K carbs that I have... The J has a coasting richener on each carb, and each model uses a slightly different set of jets/needles.

So I'm wondering what affects these differences make in the way the engine runs, and which set might be better for me to use? I don't get out on the interstate much, I mostly ride on back country roads or up in the mountains. The engine is stock with a factory airbox, and there are no plans to overbore it or do anything exotic -- I just want to get it running again. Would one set be better for those conditions? I could even mix&match parts, if I had some idea of what affect that might have.

Of course we have snow on the ground again, cold temps and more snow predicted all through next week... not good weather for working in the garage. I may just have to fire up a heater so I can get these finished up!
