Recently while riding down a trail, my bike suddenly began bogging and not running correctly. It felt as if the ignition was incorrect and was only igniting every 2 or 3 cycles of the piston. It bogged at all speeds in all gears and the only way to keep it running was by quick flicks of the throttle. Constant or no throttle would cause it to die. The piston is not seized and still has great compression. Clogged jet? Bad stater? Broken connections? Any thoughts? I use 92 octane mixed 40:1 with maxima 927 premix.
