I'm having a heck of a time starting my '09 450 when hot. I also get some popping on decel. Did lots of searching, but most of the threads are guys who have changed their pipe. My bike is completely stock (except for heavier flywheel) and it starts first or second kick when cold. Elevation here is between 500 and 1000 ft. Temps this time of year have been in the 70s. Should I concentrate on adjusting the fuel screw or do I need to change the pilot too?
