Starting a 2004 rmz250

Starting problems on your bike are usually related to twisting the throttle too often. Remember, the carb has a diaphragm pump in it that gives a shot of gas each time the throttle is twisted. That means the engine can flood quickly if you get happy on the gas. Gently use the kickstart lever to ease the piston just past top center on the compression stroke. Now give a good strong kick. Repeat as needed.

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.

if the bike push starts, i assume it runs good,
if the kick does not turn motor over, there is a spring clip that engages the kick gear that may be broken or misplaced
if the kick start turns the motor over, you have to use decomp to get just past TDC then kick

use a test light to find out if there is power going to the starter. take the rubber cover off the top of the selonoid. it should be some where near the battery. one post of the selonoid should have power constantly and the other one should not untill the start button is depressed. if the light lights when you hit the button, there is either a problem with the power cable going to the starter or the starter its self.

Stuff happens on a race bike. The problem is that it can happen so fast, with your mind on other things during a race, you don't even realise somthing happened. Another bike probably kicked up a small rock and aimed it at your carb.

YOUR VALVE CLEARANCES NEED TO BE ADJUSTED BACK TO FACTORY SPECS...IN OTHER WORDS GET IT SERVICED AT A BIKE SHOP

i got a 2000 rm 250 and it used to be a cow to kick over i used to spend at least 20 min kicking to start it until i rebuilt the top end with a new piston and rings now it starts on the fourth or fifth kick if that doesnt help you need a new cpu good luck!!!!

I have same bike and know some about it. and i race a lot. your bike has a crank or rod whatever you want to call it but it could be cracked, broke, or even could have dirt on it.

Put the bike in 3rd, 4th or 5th gear, the higher the better. Sit on the bike, with your hand off the clutch lever, and rock the bike back and forth to rotate the clutch hub. This might free up the lever. You will need to drain the oil and remove the right side casing to see and service the kick starter. If I recall correctly, there is a spring clip that allows the kick gear to engage the clutch hub. The piece could be broken, weak or out of position.

Please rate this answer. Thanks Shay!

check your ground wires to frame . scratch a little to get the neg. side grounded. also motor to frame. clean around bolt heads.
