Wont shift into neutral

Just turn the car on, but Dont start it and put it in nutruel then start it... This she work til you can afford to fix it...

your shifting paw or drum is bad

1. Yes, this is a major issue! Its not the shift drum cam unless its broken in half. It might be the shift forks, Won't go into any gear? Is there spring pressure in the shifter or does it flop? Is the shifter TIGHT on the shift shaft? I think its time for a professional to look at it.

To the RIGHT of the Shifter, there is a little door, you push a KEY down into that hole to release the Shifter

Your shift lock actuator is not working. This system works off of the brake light circuits. The FIRST thing to check is your brake lamps. If they are not working, that is the reason for your shifter not working. Fix the brake lamps and your shifter will shift. (Possible defective brake lamp switch).

If your brake lamps are working, then the shift lock solenoid or its circuits are defective. In this case, you can work around the problem until you can get it fixed. Turn the ignition switch one click.(Far enough to unlock the steering wheel, but not far enough to make the lights on the instrument cluster illuminate.) The shifter will then shift out of PARK. Place the shifter in NEUTRAL and start the engine. You can then shift to the desired gear to get where you need to go. If you place the shifter back in PARK, you will have to shut the ignition off and repeat the process.

personally I have never heard of a chain breaking and having any affect on the transmission and shifting. although if the chain broke and caught the shifter, it may have pulled the shifter so hard that it could have bent the shifting forks inside the transmission.. this would explain most of your problems..replace the chain,and with the bike "off" and in neutral, on level ground, rock it back and fourth about 6 inches and try shifting from neutral to 1st and then back up to neutral, and then to 2nd. keep rocking the bike back and fourth while doing this and do this WITHOUT using the clutch. If it wont go to the gears easily, the shift forks are likely bent. there is a safety switch for the kickstand that will shut the bike down if the kickstand is down and bike is in gear. if the kickstand is up and releasing the clutch shuts down the bike, the chain may have damaged that as well. Hope this helps..

pull your clutch in on the left handlebar push the shifter lever down and let you clutch out slowly while giveing the bike a lil bit of gas. But if you don't know how to ride i wouldn't be jumping on a kx 250

Get help, have helper hold set parking brake and hold foot brake, pop shift cable off of linkage bracket on trans, try to shift it by hand. Only starting in N may be broken internals on neutral safety switch.

It sounds like you bent the shift fork, or at least the shaft that penetrates the case and holds the shift lever on the outside. If you are certain you are moving the shaft and the bike won't come out of first then you will have to open up the case and see what is bent or broken inside.

I would inspect the shifter linkage and maybe check the belt for damage.A little wd40 might help.
