    Bro let me explain how the meter works.
    There is a small ring inside near the front wheel hub known as speedometer pinion. When the front wheel rotates the pinion rotates which in turn is connected to the speedometer cable. When pinion rotates it will rotate the cable. When the cable rotates it will rotate the needle in the speedometer which is connected to it.
    Now remove the front wheel and check which is fault and replace it. And for your info,a speedometer doesn't need electricity to work. When you're removing the wheel make sure you don't mess up with the brakes.
    Hope this helps you.
    thanks for the reply ,do you know where can i find a replacement for the speedometer pinion , mine is missing so the gear and cable doesnt rotate with the wheel, even if it came from another bike its okay it only needs to fit in the gear and rotate with the wheel

      Finding a speedometer pinon for an old bike is difficult of course. I don't think there is any substitute for it. Even if we change pinion meter won't show accurate readings like original one. It will take time for meter needless to get set to new pinion and cables.Finding an oe spare is near to impossible. Did you check the pinion. Is it spinning. Check whether it is fitted in reverse direction. Change the direction and see.BTW where are you from. If you're from Coimbatore or Trichy you can get it in Aditya or dj automobiles. Man they have everything.

      Same thing happened in my KB and I had to change the pinion. But I am not getting accurate Speedo readings. It's like I'm at 10 but it shows 20 and when in 60 it shows around 50. You'll get some 7-8 kmph difference. It'll take time for needles to get set.
      NEEDLESS
      IT'S NOT NEEDLESS is needles.
