I took my warrior out yesterday I couldn't get any power out of it adn it was popping really really bad. I changed out the plug and put in a new filter. The option that I was told was maybe the spark plug wire could be grounding or the timing could be off.
here is what i would check first..there are two things that make the ignition not fire right. one is a wire that grounds into the reverse switch, make shure the connection is clean and solid. two is the parking brake. if it is too tight it will make the ignition mess up either loosen the cable up or deactivate the switch
