check your carbs. it might be dumping to much gas in that cylinder, causing the plug to fowl out and have a weak spark. make sure the carbs are adjusted and then sync them for proper fuel air mixture.

Rm 250 wont start off kick


Don't know if it is water cooled or not, but it sounds like you may have a problem with oil or water getting into the combustion chamber and fouling the spark plugs. Kicking doesn't produce the amount of rpm that you need to fire up a weakly firing plug. I'd check the plugs condition first and replace if needed, and then figure out why its smoking.

Well the motor locked up and i couldnt kick it at all shifted threw all the gears just fine but i wuz messing with it and i ran through all the gears trying to turn the back wheel and knock it loose didnt...


If you are running 5th gear mid throttle the compression in the motor wasnt enough to push the piston back down

for the record ( i run a ts 250 savage 2 stroke ) i,ve done it my self it happends

try to keep it the power band you will be fine

good luck.

Hard to start


fresh fuel, drain old out of system, clean air filter and fuel filter clean spark plugs and kill switch(use electric contact cleaner on switch.)if still hard to kick start clean the carbs out.if trash or water is in the system the jets and needle valves are probably dirty as well.

2005 Rmz250 wont start when hot.


YOUR BIKE HAS A POWER VALVE (DIAPHRAM FUEL PUMP) THAT GIVES A SHOT OF GAS EACH TIME THE THROTTLE IS TWISTED. WHEN THE BIKE IS HOT, IT FLOODS EASILY. DON'T HIT THE THROTTLE WHEN STARTING THE BIKE WHEN THE ENGINE IS HOT.
