Headgasket leak?If you have not done so already try filling up the rad(when cold) and run the engine with the rad cap off and look for air bubbles, or you could go to a radiator service centre to check for carbon monoxide in the rad.

Please get back to me if you require further asssistance.

I have a 2004 Yamaha YFZ 450 the bike will start and drive but as soon as it warms up when you push the throttle it starts to cut out... What is the problem?


There is not really enough info in your post to narrow down the problem. Hesitation during acceleration can either be fuel related or ignition timing related. Once up to speed, will it maintain that speed smoothly?

If you have a timing light, check the timing at idle. If it is OK, then it is probably fuel related.

Assuming you have not messed with the ignition timing, if it idles, but won't accelerate, it is probably starved for fuel. 1.Check/change the fuel filter- easy and cheap
2. pull the fuel line off the carb, and make sure fuel flows from the tank freely.
3. If there is good fuel flow to the carbs, pull the carbs and clean them.

I have a 2004 yfz 450 that wont idle, not sure why anymore


Hi, Anonymous and the usual suspects are:
1. Idle circuit and transfer ports clogged.
2. Air fuel mixture adjustment too lean.
3. Pilot jet clogged.
4. Faulty accelerator pump.
5. Float level too low.
6. Float bowl contaminated old fuel, water, dirt, rust, etc.
7. Float bowl vent or overflow tube clogged.
8. Fuel flow to carburetor restricted.
9. Intake manifold leak.

Turn the idle screw anticlockwise half to one turn to set if this does not affect idle speed then you need to look further inside carbi or intake valves for other issues

04 yfz 450 wont start with electrical start


i have a 04 yfz 450 quad. the compression ratio like yours is extremely high. ive had my battery go bad and found that another battery other than factory would turn over the engine, but would not start. i paid the 100 dollars for the factory battery and it fired right up. because of the high compression you need a high cranking battery.
