What pipes are you running? You say your running a K&N, is that in the air box or pods? Are you running the air lid?
When I had my stock ported motor with T6's I was at 162 main, N68A needle in the middle, 45 pilot. I tried running running the carbs with the airlid on and it just didnt seem to want to run right (I tried mains from 148-165). As soon as I took the air lid off it ran like all hell.
im using stock pipes right now and im using a k&n filter w/outerwear in the stock box with the lid on.
i just bought some fmf gnarlys to go with the filter. i never thought of running it with the lid off,maybe she needs the lid off. wow! thanks guys, for your help, much appreciated!
