[QUOTE="penguin, post: 141874, member: 17399"] for a box stock KLX300 ( no internal engine mods) the 33 mikuni pumper is the best bang for the buck and the easiest of the bunch to get jetted right ( I got mine from Stroker and never touched the jetting). To receive the maximum benefit, you need the oversize header pipe. You do not need the aftermarket muffler, just remove the restrictor from the end of the stocker . The power still remains tractable at low speed, but when you grab a handful of throttle the bike comes on the pipe a lot faster. You have to cut the frame at the right side headstay bracket and fabricate a spacer to put under the back of the fuel tank to make the carb fit, but the 33mm mikuni is the way to go. The 36mm mikuni is getting hard to find and hurts low end response, and the 35mm Keihin FCR hits too hard right off the bottom and would be a handful in slippery conditions. I just sold my 35mm FCR and plan on getting another 33mm Mikuni in the next few months [/QUOTE]
