I just finished installing a cobra FI2000R fuel processor and a Cobra Power-flo air kit. I took it for a long ride. They have definitely made a big difference in performance. The install was fairly simple. One injector was a pain to get to. I love the plug and play setup. It was a bit pricey but hopefully worth it.
I just got a new (to me) 2007 900 custom and this one has Cobra Dragsters on it. Boy, are they loud. I even like the back-pop when I'm in too high a gear (like when I'm slowing down and then give it some gas). They're stinky, but loud.
Sage1965 - in what way do you feel that the Baron's front pulley is better than the SW. I just put the SW front pulley on and although I only have 300 miles with the new pulley it has been flawless. Can't imagine in what way the the Baron's could be better.
