For sale ser#keihin pz carburetor from taiwan not china. Genuine keihin main jet, new style keihin pilot jet and float needle and brass seat. this carb has been bench tested, tweaked for optimum performance and rejetted for sea level operation. The written numbers on carburetor indicate needle position, main jet size, pilot jet size and fuel mixture screw turns. This carb can be rejetted for customer specifics including altitude and motor modifications just send me your specifics after purchase. I will include an extra step up in jetting in case modifications are done to the engine later. I currently use these on my rebuilds to include crf150f,crf230f and xr200r with great success. When using on a xr200r the carburetor is smaller than the intake but does bolt on and seal working fine. Most of my engines have minor modifications such as exhaust, airbox and filter(un snorkeling) , performance camshaft, performance cdi box and even some of the cheap big bore kits. I’m not claiming this to be the best carburetor ever but I have found a specific vendor from Indonesia and a carburetor that works great besides the expensive oem carbs or used wore out carbs that are being sold with the premises of you needing to rebuild it, maybe they work maybe they don’t. I have a 100% positive feedback and encourage you to wait until you use this carb to leave feedback on its performance. Note you will need a separate throttle cable that is not pressed into the top cap. I will have these listed on a separate listing and will throw them in the box for no shipping cost. This is the last one I have currently.
