Idle jet has probably got blocked, there are two jets, an idle and a main, when your bump starting it is most likely using the main jet and when you decreas the throttle it is coming onto the blocked idle jet. take the idle jet out of the carb and check it.

I have a 2000 CR 250, has always ran perfect and now will not start or fire. It has spark and is getting fuel to the carb(cleaned it spotless) air filter clean also. Fuel is fresh (use non-ethanol Supreme)...

Try starting it with a brief spray of ether into the intake. If it runs briefly it indicates a fuel/carb problem.

If it doesn't run the problem could be spark related, poor induction due to crank seals or other air leaks or perhaps oil is settling in the crankcase and corrupting the incoming charge.

Deceleration popping on a fuel injected bike

Hi Anonymous, popping, coughing, spitting, or backfiring through the carburator or induction module can be caused by air getting sucked in combustion chamber do bad intake seals leaking. Leaking exhaust gaskets can also be suspect. Remove air cleaner and backing plate, while engine is idling spray WD-40 or Brake Kleen around intake manifold to head area, if RPM's increase you have an intake leak and seals need to be replaced, also spark plugs will be burning whiter than normal. Good luck

My C50 Intruder Volusia backfires when decelerating.

If it has aftermarket free flowing pipes on it, it is due to the unburnt fuel popping in the header. You just didn't hear it before because the mufflers muffled it. Otherwise, I would reccomend you check for an exhaust leak

I have a 2005 tc 250 and it refuses to kick over. I put a battery in it and it started then died after 2 mins of idling. Battery died so I tried kicking it at tdc, will not start. Fuel is on, choke in or...

Have you checked for a spark? or done a compression test? You may need to adjust the idle screw or tick over screw slightly 1/4 turn at a time (remember where you started.)

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
