mac exhaust and jets

[kwells]

I have an '82 with Mac exhaust and was wondering if anyone might know what would be the ideal jets that I should be running. ?I was going to buy the kiester carb rebuild kit but didn't want to purchase the wrong sized jets since I no longer have the original specs. ?Any ideas would be appreciated.
The bike seems to want to die out until I really get on the throttle and then it takes off but until then it wants to stumble...would this be a product of the jets?

I have stock jetting with my Macs. i've run them with both 83 & 83 carbs...  I'm one of those guys who can't tell the difference beween 'light sky blue & baby blue'.. so if I were to fine tune for jetting I probably couldn't tell the diff...  but the bike runs great, and the plug colors look great.

Just cleaning the carbs maybe enough to cure that.  My 82' had MACS on it when I got it and I have since removed them in favor of the factory chamber exhaust (1 pipe on each side) I had a stumble for months until I bit the bullet and just cleaned the carbs really well and then sync'ed them and adjusted the mixture screws.  It was an ongoing battle for a while but it has been worth it as the bike has never run smoother or quieter.

I have unfortuately had to clean these carbs about 5 times...sounds excessive but ended up having some gunk in my tank giving a perpetual problem.  I know now that I have to resync the carbs...again..I don't have the manometer of the homemade version but hope to this week.   I noticed that one of the o rings on my mixture screw is missing and can't seem to find anywhere that carries an o ring that small. Anyone know where I might be able to get these?
