Question about 2003 Yamaha YZ 125
I went to start my yz125 2001 an on about the 3 third kick the kick start just locked up. so i took it upart an couldnt find anything wrong. have uyou ever seen or heard of this if so could you let me know what it could possably be?
1). Confirm that the transmission is really in nuetral, or insure that the clutch is pulled in.
2). Have you tried removing the spark plug to insure that you do not have a hydraulic lock due to excess fuel in the cylinder? With spark plug removed, any excess fuel should be expelled out the open spark plug hole. CAUTION: INSURE THAT THE SPARK PLUG LEAD IS DISCONNECTED, AND HELD AWAY FROM THE OPEN CYLINDER TO PREVENT ACCIDENTAL IGNITION OF EXCESS FUEL.

the engine is locked up..you can try and spray some lubrication in through the spark plug hole aand let it sit awhile..make sure your oil is full and the right oil...once it has locked up and you break it free, the chances it will lock up again are great

Kick it on the otherside,,,,,, Perhaps your starter motor brushes got jammed, well off to a repair shop or if daring take that motor apart.

Sounds like it either dropped a valve, or broke a Connecting Rod. It is never good to get the RPM's too high on the first start. If you have to get them up high to keep it running, you probably have build up in the carb. Make sure it is in Neutral, and the first thing I would do is check the valves. Lift the valve cover off and see if any of them are missing. If not, unscrew the side cover on the left side of the bike(1 inch round cover using a flat tip screw dirver) and the nut in there that is exposed, try to turn it with a ratchet. If you cannot, pull the spark plug and using a pick up magnet, run it down the hole, swish it around a little, pull it out and see if you picked up anything. Last thing I can think of is drain your oil, and see if any metal comes out there, if not, your going to probably be rebuilding. It's not as expensive as it sounds if you do most of the work yourself and pay close attention to your service manual. If you need one, I can send you a digital copy for $30, or a grease proof binder and CD for $100.
