I have Dave's mods and they are good, but my CV carb still sucks for throttle response, so I am putting an FCR 41 on my 06 650L. I live in Bend OR, at about 3400', and many rides go up in altitude from here. Stock piston and cam, desmogged, Pro Circuit 496 slip-on pipe. I got the baseline from Burned, but I'm looking for comments and jetting info from you all. Anyone have any feedback? BP ride.race.live.
