Hi,,,,check your coolant level,,,,also might have an airlock,,,take off the radiator cap when the bike is cold and start it up let it warm up and make sure there is coolant to the top of the radiator.

check that the radiators are clean from mud ect,that blocks airflow.

2004 YZ 250 F: I just bought a 2004 yzf 250. How do I chech the o...

Put the bike on a stand or make sure the bike is level and upright. Start the bike. Let run for 1 min. Shut down. Let sit for 5 minutes. There is a dipstick on the frame below the handlebars on the left side of the bike. Unscrew and check. Another important check to do is to check that you have pressure. On the back side of the head, you will see a metal line running up it. Just to the right of the top of the line you will see a 8mm bolt. This is the oil gallery bolt. Loosen it quite a bit and start the bike. if within one minute you do not see oil seepage from it, you do not have oil pressure. Shut the bike down as this will seize the engine within a couple of minutes. If you have pressure, tighten the bolt back to 7.2Ft. LBS. I suggest you get a service manual for this bike though as it has alot of important information that can help keep you from making costly mistakes. I can send it to you for $30 digital, or $100 grease proof and digital binder copy.

I have a 04 yz250f that over heats at idle ?

All of the yzf,wrf models WILL overheat at idle.They need air to be going through the radiator at all times.What this means is if you are going to be stopped,for anything but a very short time,turn the motor off.Even after a short time the header pipes may start to glow.These motors are quite high performance and they need the air flow.Hope this helps

A no start when hot starts and runs good when just warm or cold no start when fully warm

There is a sequence to follow when these bikes are hot to get them started.But first.Does the bike start easily when hot if it is push started? If the answer is yes,you need to use the hot start pull switch on the carby and the get the motor in compression before you pull in the small compression lever and slowly push on the kickstarter halfway down.Release lever and fully kick the motor over from the top of the kickstarter.Don't let these bikes sit around idling.They will overheat because they need air to get through the radiator.Hope this helps
