I picked up a stage 1 kit for cheap, so decided to play a bit.
Running around town, and the rpms around 2000, I would almost get a lean surge...and the bike felt really "peaky" is really the only word that I can use. My setup is 147.5's, Kerker 4-1, A/F screw 4 turns out (I like the sound), needles shimmed 30 thousands, and "Y" removed.
With the stage 1 kit, I decided to swap diaphragm springs. All I can say is WOW....it has smoothed out the bike around town, and really woken it up. I guess that I was lean, and making the needles come in earlier helped.
