hi everyone, just started on this forum and i hope to learn alot. My brother has an 02 edge x 600 that runs real rich throughout all throttle positions. It's especially rich on the bottom. I've tried adjusting the idle mixture screw, with very little luck. We've also installed a hot seat boost bottle. I'm now thinking of jetting down on the main jet or even just a pilot jet change. We had a 2000xc sp 600 (genII) that ran right along with 700s all day, and this 600 barely breaks 105 on the speedo and runs more like a ves500. I do understand the gen II chassis was faster, but gas mileage shouldn't have been dropped from 15-16mpg on the 2000 to 10-11 on the 02. Any thoughts or good carb set ups out there? I sure miss that 2000 600s performance and would like to see my brothers 600 be a little closer in performance. Thanks for any tips. I appreciate it
