Lost my key to my 1996 kawasaki ninga 250!!!! How to bypass the key switch or hot wire it to get it home???,

You will have to get a duplicate key from the dealer or have a locksmith make a key. If you attempt to bypass the ignition switch you will trigger the anti-theft function in the ECM and disable the vehicle. ALWAYS KEEP A SPARE KEY TO AVOID EXPENSIVE LOCKOUTS

Does your new switch have a resistor in the bottom of it as the original one does but cheap copies don't and it will not spark if it has no resistor,I have been here before with a gpz500 s

Short of removing the ignition lock and manually hot-wiring the bike, you'll need to have the lock replaced. But if you ride around with an ignition hot-wired you're bound to get stopped by police or risk having the bike stolen unless you hide a bypass switch somewhere. You could try a locksmith but you're best bet is to either order a new one through a dealership, online or find a parts bike and take it from there.

DO NOT ATTEMPT to "hot wire" a solid state ignition system!

Start there.. use the next few pages....

Check down by the battery and the fuse box area and make sure that all the fuses are good. It may have blown a fuse when you where hot wiring it.

hi there, it should be a screw on the same mount as your clutch lever, with a seperate cable leading down to the right hand side of the carbs. alternatively, there may be a knurled adjuster on a cable sticking out the side of one of the fairings. hope this is helpful

You go to the dealer and ask them to get you a new key (take the ignition switch, or the bike with you!

DO NOT ATTEMPT TO HOT WIRE THIS BIKE!!
