Bike pops on deceleration. hard to kick start,cold blooded
SOURCE: yamaha 2003 wrf 250 start
hey m8,, sounds like u have a bit **** in the carb floating arround the jets m8,, wen its warm and bein used the dirt will flow round the carb untill left overnight to settle ,,that will block the fast idle jet,, need to take the bottom of the carb off,,ie the float bowl wip out the jet that the needle sits in to,, this will have about 4 little holes threw the stem of the jet, poke a pin or needle threw them and the main jet,, untill u see light threw the holes,, clean out the float bowl,, that should sort it,,

Please rate the solution as a "FixYa" if able. Thanks!
SOURCE: no idle &bacfires 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

Many of those CRF have problems with the valves, check the valve clearances, as well as all the general maintenance items, clean carb, clean air filter, new plug.
If the clearances need more than one number smaller on the shims, it may be the start of valve regression.
