I have scoured GOOGLE and SEARCHED through threads. Will a TM31 (DR250 "dirt model pumper") fit on a 2007 KLX250s? When I mean fit, I mean "run proper or correctly". The most info I have found,so far,was that it's actually a 31.8x almost a 32 basically. Could it sent it off to be made into a 32plus? I am looking to keep the stock 250 jug on there for the time being and do the sproket,intake and exhaust mods.The bike will be mostly ridden on trails and around town. Probably no serious highway use for the time being. (being a 250) The carb is going to be coming with the throttle,cables,intake boots etc...from the 90' DR250. Looking for "snap" throttle throughout the powerband,250 wise. The carb was a good deal considering what I would of spent on jet kit etc.. Thoughts, concerns, considerations? Thanks. EDIT: Elevation..ahhh forgot, I Live in Denver,~MILE HIGH~ because the air is thinner up here what would be the effects on running a smaller carb? Less air = less fuel to be run in a carb.Meaning to me,No need for a TM33 at this alti to get the same effect as needing a bigger carb down south. OR, does this mean I am needing a BIGGER carb to make up for the lose of air. again,not looking for great gains,just "snap" in throttle response,considering the stock CVK uses vacuum,air,for accelleration,correct?
