I was riding my rmx 250 and it suddenly died! i kicked it again and started and died again. i tried to start it again and the kick shift wouldnt move. what would cause this
Sounds like a seized motor to me............if kick starter won't move!!!!!!! That's how my KX250 went when it seized. A mouse chewed my filter up & sand got into the motorSounds like a seized motor to me............if kick starter won't move!!!!!!! That's how my KX250 went when it seized.

How does the compression feel now that you have it cranking over again. Without the decompression lever pulled in it should be next to impossible to kick it over. also, is there any noise coming from the engine (knocking, etc.) when you got it to start again.
Remove the spark plug, put the bike in fourth or fifth gear then try a jump start but with the key turned off. If the rear wheel locks up when you jump on and release the clutch then the piston has probably seized up OR the kick start-to-clutch hub gearing is messed up. The best thing to do is to remove the left engine side cover and look at the kick start mechanism. You may need to remove the clutch assembly for a full inspection. With the clutch removed the rotor ( crankshaft flywheel ) should turn. If it will not turn then a seized piston, broken cam chain or dropped valve is likely. If the rotor does turn then the kick start mechanism is the problem. Please rate my answer. Thanks!
check inlet valve clearances. they close up making it hard to start exactly as you described. titanium valve coatings wear and ressesion happens quickly,a clean air filter must be maintained to prevent contaniments wearing valve coatings.
I recomend you to take a compression test.
From your explanation it seems there's no compression at all thts why the engine rotates easier on kick start.
Check the sprockets. Got a stick or rock binding the chain? Remove the chain. Does the wheel spin freely? Brake frozen?
Since your bike is water cooled, a seized piston is not too likely. Got water in the radiator? Most likely is a broken torsion spring on the kick start shaft. The adjacent ratchet wheel and the kick shaft should be inspected. The ratchet wheel should have a smooth movement. If not then replace it. The kick shaft should not show wear or damage. The same is true for the kick gear and idler gear. Replace as needed.
The only other possibilities are a frozen main bearing, (not likely), a broken or severely bent shift fork, (more likely than a main bearing).
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.
