When i try and start my yz250 it never starts but when i take out the spark plug and rinse of the oil with gas and pour some gas in the cylinder head it starts right up ... whats wrong with my bike i dont want to take out the spark plug and do the same thing each time i want to ride.

Sounds like it’s not getting gas from the carb. When was the last time you cleaned your carb? Ethanol pump gas breaks down in just a few weeks and can really gunk up your jets and all the little circuits and passages in the carb

You should PULL the carb off the bike and make sure youve got ALL the premix (gas) drained out of the carb and with the carb assembled in your hand (nothing on it removed) try toBlow through the fueling entrance of your carburetor and see if you have unrestricted movement of air if you do then it’s highly likely your bike is getting gas like there’s a blockage at that point you should check out

Right, because once the engine is running, it's able to suck the gas through the carb; but just kicking it over isn't creating enough suction to draw the gas through the carb - because your carb needs cleaned.
