I run a 45 pilot with a 165 main for summer but switch it to a 168 in the winter. All my other jetting is stock.

put a 48 pilot in, and start around 1.5-2 turns out on the fuel screw, your popping problem should be fixed.


got a new fuel screw, needed washer and oring... pit in a 48 and set FS to 1.5 out. I checked the cam lobes with the sprockets when I had the head cover off and after I timed it and they seemed in the right position from what Ive seen on other bikes. I have yet to start it after the jetting, but my friend was in town... anyway now my KXF has issues with a zinging sound, I love 2 strokes.
