Well, I fixed my problem...I pulled the stock carbs out of retirement and put them on it, lol. Runs great now!!
On the 2 into 1, I installed the power jet and was able to get enough gas to it so it wasn't lean, but I still had the problem with it cutting out by 4th/5th gear. It boiled down to the bowl was being sucked dry. Fuel petcock was clean, gas cap breather was working properly, everything checked OK on fuel delivery, but for some reason the bowl just wasn't filling up fast enough :shrug: I slapped the stockers on there w/ a 27.5 pilot, 310 main and it ran great last night. I still need to take it out and put a really long pass on it but I think I got my issue resolved....FINALLY! I just got tired of dicking with it, and with the weather warming up, I want to ride this bastard, not work on it, LOL
So....my 2 into 1 setup will be for sale. 2 into 1 intake, 38mm Keihin PJ carb w/ adjustable power jet, Trinity CV airbox adapter, and pod filter for the carb. The carb also has a terry cable but you may have to re-tap your throttle assembly for it to fit properly. My threads were slightly different. PM me if anyone's interested, I'll also be listing this in the for sale section, with pics :beer:
Thanks for everyone's help along the way
