I have a 12 port stroker motor from Jim and am running stock carbs (they suck I know). I have 25 pilots, as the bike wouldn't idle with anything larger and it constantly wanted to load up and blubber when trying to putt around. The needle is a dynojet needle in the 3rd notch from the top. Mains are 370. My problem is that when in fifth or sixth just cruising along at say 1/3 throttle and nail the throttle, it takes forever for the motor to come on the pipe. I'm thinking that it is running too rich in the midrange and can't pull itself on the pipe. My reasoning for this is, it was worse when the clip was in second notch from bottom. I know, I know, raise the f#@&ing clip idiot! It also gets worse as atmospheric temps go up. Heres the clincher though, my friend has the exact same port job with the exact same pipes,(FMF Fatties) and exact same gearing, he was so frustrated that he stuck his stock needles back in and its still too rich. So where o where do I go from here? It runs fine when putting around in 1-3 and nail it, it will jump on the pipe rather quickly and is a load of fun. It runs like a scalded hog when its on the pipe and it will keep scalding him if you're raping it through the gears, its just that the roll on power sucks balls. I was hoping not to resort to spending another $500-$600 on gdamn carbs already. Someone help.
