the other day i went to take my yfz for a quick ride, i got a half a mile down the trail and it just quit, its like it blew up. i went to start it and it wouldnt turn over, the engine was stuck. i moved it forward a little and it unfroze and started again. i went to take off and it did it again. so today i changed my oil and took it for another ride. it did it again. it keeps wanting to stall. it doesnt backfire or anything, it will just bog a little and lose power. it will idle but will instantly stop running after a few seconds. whats wrong???:( :confused:

that doesnt sound very good...

Sounds a lot like your rings are shot making them seize and unseize to the cylinder wall. Try removing the spark plug to eliminate the compression and turn the crank over by hand with a ratchet. If it is very difficult to turn over or stuck, then there is a good possibility your rings are cooked :( . Good luck with solving the problem :)
