2004 kxf 250 kawasaki dirt bike,wont idle &backfires.pops on deceleration.
Hi mate on the carb you will find 2 screw 1 is for the idle and the over is for mixture the idle one will be the furthest out screw it in 1/4of a turns will the engine is running this will take the idle up on the engine and the backfiring is fuel in the exhaust not being burnt so on the over screw on the carb screw that in 1/4 of turns this will decrease the amount of fuel going into the engine if it still backfires screw it in 1/4 of turns again and see what difference it makes good luck
