According to Rocky Mountain, the Kfx uses the 49033-0010 fuel injector and also in many of their bikes/quads. Try typing the stock number on Ebay and you'll get some cheap Chinese knockoffs. I would not consider them reliable though.

I was having that problem got a new battery and starter now it starts fine but bogs down and backfires in the high gears.
im not getting voltage to injector.if i turn key it should spray some right?i checked fuses found 1 blown just new that was it.still not starting;ive got almost new battery with charger hooked up believe starter is gone now.i ground orange/black no codes.what triggers the injector,tps maybe?i also switched relays.

A bad ECU, faulty vehicle down sensor & the TPS out of range can affect your injector...?
