What can be done about carb ice?
If you’re riding along and the engine starts running rough or loses power, there’s a chance you have carb ice. If switching to reserve doesn’t cure the problem, it’s very likely your carbs are icing up. On the Ninja 250, other indications are: • You must blip the throttle and hold the engine at 3,000+ RPM at intersections to avoid stalling • You must use increasing amounts of throttle to maintain the same engine speed (RPM) • You smell fuel (extreme rich condition) • The engine note changes to a more staccato sound (this means you are about to stall!) The best and safest reaction is to pull over into a safe parking spot and stop the engine. Engine heat will heat up the carburetors, and they should be ice-free in 10-30 minutes, depending on build up, ambient temperature, and engine temperature. Note that in extremely severe weather (well below freezing), engine heat will not be enough to melt the ice in your carburetors, and you may need to abandon your motorcycle and wait for a warmer
