well, i'm running a bigger main than I should be. It doesn't look super lean, but I don't have near the color I'd like, so it worries me. It runs really good, and it colors great in the midrange throttle, but my WOT is just a little lighter than I'd like and I'm afraid of putting a hole in my piston. I've checked a hundred different times for air leaks and can not find one anywhere.
I'm going to go back to the ES's because I have much more experience reading them, and then play with it some more. If all else fails, I'm going to grab one of my other main jets and start drilling to see how far she wants to go before fouling and that should give me an idea of where she's at now with my present jet.
BTW. Single carb, Fatty pipes, no internal work, VForce Reeds, ProFlo Uni, timing and some other little doodad shit and I'm running a 230 main. Biggest I can get for my Keihen. I should be around 180 or 190. The SOB will freaking run hard though, seriously, I can hang with some I feel I shouldn't be able to. My comp. is 125 even on both, lower than I'd like, but...
Anyway, I'll keep riding till I get it or she blows, but I'll have fun either way.
