    You don't say just how much voltage you get while bike is running.

    Sounds like a battery that's going bad. Just enough to run but not enough to pull higher cranking current.
    Just to make sure, put a meter on it while bike is running ( about 1500 rpm or higher. ) Should be 13 - 14 volts with normal running loads.
    If lower, like 12 volts or lower, than I'd check the alternator output or voltage regulator.

    To check the battery for cranking power, put volt meter on battery and observe while cranking. Should not go much below 10 - 11 volts while cranking starter. Better if holds at 12 volts while cranking.
    If 10 volts or lower, the CDI probably will not put out, even if you have a good one.

    Also, it would be a good idea to disconnect the battery terminals and take a resistance reading from the Pos. battery lead ( not terminal ) to the bikes chassis. You should not have a short circuit reading.
    Make sure all switches are in OFF position.

    If you do get a low resistance reading, check for stuck light switches, shorts in wiring, bulb sockets shorted, etc.

    Here's a link to the NX's ignition section in the shop manual. http://powers31.info/1988_NX250_Ign_Sys.pdf
    May help you in trouble shooting.

    I was on a ride a few months ago and would lose spark intermittently. Sometimes I would have a headlight, sometimes I wouldn't. I pulled the tank plastics to get to all the connectors (my electrics are 'custom' to say the least) and couldn't find anything wrong. I was jiggling the wires to try to find the loose connector, and my positive terminal bolt was almost falling out.

    Sometimes the simple things are the things that hurt the most.

    Anybody have a front brake caliper? Jill's bike has the pin bolt for the pads totally frozen and stripped. Took me forever just to get the little threaded cap that protects the allen head of the actual bolt out, only to find that the bolt itself is phucked.

    Don't stress, check ebay and see what is there. I had to get one a little while ago and a few folks helped.
    I don't have one you can have but I know that you can get any other two pot caliper and get a bracket made up
    for mounting on the cheapo.

    UCRONIANO welcome / bienvenido
    thanks for the info.

    The bash plate you got going is one of the better looking solutions yet and it looks like it would protect the water pump some.
    However that is not what you find stock on a 85 xl250r here in North America or at least not on any of the ones I have seen. It is encouraging to see that other plates can be made to work.

    How involved was it in terms of fitment? Cutting, drilling etc.

    Speaking of electric problems. I had the headlight going out for a while.
    It totally drove me nuts, as I like to ride lights hehe.
    Tried to diagnose the problem for a while using all sorts of checks and yaddy yadda, nothing.

    Then I started it one day and the light was on and I was like what the hell.
    Pushed the start button again and the light went off. Turns out the starter switch was cutting the light as it is supposed to while starting to save juice but the button was not springing back far enough to engage the switch again.
    Simple thing but can cause grief.

    Thanks for the help with the GPS guys - I decided to just purchase a battery tender and a female cigarette lighter plugin - it worked perfectly and was very easy to install, even for me :D

    However, I have another question - If I leave the charger of the GPS plugged into the female cigarette port, but have the charger unplugged from the gps, will this still drain the battery? I think the answer is yes because even with the key of the motorcycle off, the GPS charger still has a red light glowing on it, which means it's getting power. I say this because if it didn't drain the battery I could simply store the charger under the seat of the bike and keep it out of the rain, and then simply run the end that plugs into the GPS up under the gas tank and that would be the only thing exposed.

    Arthduro Hi, thanks for the welcome, this forum is very good.
    About the skid plate, the bike here in Chile is very common xl250. You can use other similar off-road bike ... which I installed on my bike had to be cut and drilled in their ends in only two sectors for installation,had to be bent manually, I am very securely and protects the water pump to perfection, greetings!
