My 01 yz 125 is running really strange

Ok, well my bike starts up usually sometimes not on the first kick, and then than when i give it barely a little gas it bogs down then i have to put the choke on and it fires back up, so i turn that off and try it keep it running and it usually bogs back down and shuts off, sometimes when im ridin it and im slowin down ill pull the clutch in and it will have died while i had the clutch pulled in and i was coasting... 1 more thing, is it supposed to leak drops of oil from the bottom of the bike? im not sure if it's supposed to but mine does

    No, it is not supposed to leak oil. A couple drips overnight probably is not serious but you should find out where it is coming from.

    The symptoms you describe could be caused by several things. The easiest to check is the air and fuel filters but carburetor trouble is the most likely. Check those things and post back with your results.

On my yz 125 my kick start is jammed

Were you riding it when it jammed because that could mean the that something is sized inside the motor, like the crank or the pistion

Sometimes it goses backwards

If this problem only happens after starting the bike it will be your timing.

Check that your pickup coil is aligned correctly aprox 2mm BTDC and that the pick up wires are the correct way around.

If the timing is after TDC it can start the motor in reverse when kicking it over.

Hard to start yz250 dirt bike 2001 4stroke

i used to own a yz426f and it had the exact problem... a fresh plug will fix your problem. change the plug and the bike will run great. also don't start the bike and shut it off , my bike would be fine if i started it and rode for a while getting to the proper heat range help save the plug. if my bike didn't start in one or two kicks it was usually the plug.



hope this helps
