    do you know how the time might slip

    I think that you need to check that you haven't holed the piston or blown the head gasket. Very common on 2 strokes.

    Have you changed anything at all since last running the engine, or a few weeks before it dyed?
    Like the exhaust being changed or plug?

If you are getting a nice bright blue spark then no, the last time I had a problem like this it was sugar in my tank. If you taste a bit off your finger and it is the slightest bit sweet, then some one has sugared your tank. If so just flush the tank with a little fresh fuel and then flush the carb, and fuel lines by spinning the engine over for a bit then try to start again.
Is yours an electronic ignition or points. If points gap could be wrong or even timing slipped. That has happened to me also.

A yamaha warrior isnt a 2 stroke. they make a street bike nad a four stroke quad. Check your carburator. check your spark plug and check your stator. it may be very minor considering it was running fine then just went out. no noise or anything. you would have heard something if you broke something internal.

My yamaha raptor has power, spark, fuel and will turn over, but won't start.


Check the compression, pull the spark plugs one at a time if more then one. If you don't have a compression gauge, you can put your figure over the spark plug hole, be mindful that before it blows it's going to **** so make sure that you don't hurt yourself leave a little gap so your figure doesn't suction down to tight. If your getting compression it should **** and blow pretty hard. If it seems to have good pressure and suction. You might need to check your timing, also make sure that you can feel air moving out the exhaust, might not be able to with the pipes on it but if it won't start and your getting everything else it needs to run gas,spark, etc. It has to almost be timing or compression.

Try checking the switch for your parking brake. It is the top wire in the clutch handle boot. This wire connects to your CDI box, and restricts the RPM's while the parking brake is engauged. To find out for sure, trace the wire down to the plug under the headlight assembly and disconnect it. Now try starting you machine and give it some throttle!
