125cc pit pro, pit bike Kick start lever jammed


remove the cover that houses the kick starter and look for a failed return spring or some other reason that keeps the kick start dog engaged.

Hi i have a 1995 yz250 the bike was fine till one day it wouldn't kick only bump start so I cleaned th carb and the filter then the bike started 1st 2nd kick about 20 mins of riding later the bike...


Hi mate I would be getting someone to check resistance on your stator its a simple test only requires a multimeter but hard to explain on here - From what your saying I think this test could save your headache!
Once stators fail they can be completely unreliable such as allow you to push start but not kick start or allow you to start but as soon as bike warms up fails completely until cold again they even can give false reading when you test to see if spark is at the plug as you see spark but is not strong enough or is sparking at wrong time... I have had bikes come in my work shop where guys have been confident has spark and they have rebuilt and replaced everything you can imagine but all it was the stator failing with not enough resistance..

At full speed in 5th gear on my 1990 YZ 250 WR (wide ratio) the rear wheel locked up. I turned off the engine. I was able to start the engine again on the 1st kick. I was able to ride back to camp in 5th...


Hi, Rvptough for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Bike wont start, lights come on, has gas, wont kick start either


1st is all the way down, neutral is between 1st and 2nd. Sometimes hard to find.
The problem is probably a dead battery. Try to start it using a jumper cable off the car (if you know how) Get some help from someone who knows something about motorcycles.
Please have your son take some kind of lessons before he rides much. I don't want to cast a pall on his fun but he will be better off. (And live longer)

Kick start has no compression but runs fine once i get it going


Does it feel like yhe kick is even engaging and turning the crankshaft? Are you full stroking/kicking it over or short stroking it? when cold, are you using the choke. I suggest taking a compression test when it feels as if it hs no compression It could be undersized piston, rings, or a simple. good luck

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
