    Rev clock

    Hi,
    I started up my bike today and let it tick over for a few minutes before taking it for a 20min spin out the road. Got my jacket, gloves and helmet on, sat on the bike and noticed my rev needle was dying a small bit. I gave it a bit more choke and put it down to the cold weather, but was a bit strange, as I thought it had warmed up enough....

    Went for my spin and didnt really notice it untill I got home and as I pulled up on my drive my rev clock/needle got lower and lower and then just went to "0" and stayed there.

    I put her into neutral and gave it a rev but nothing. Didnt the oul "turn it off and on again" trick, but no, my rev clock is dead.

    Speedo is fine, and its ticking over great. Even adjusted the idle slightly but than didnt move it either.
    Could it just be a simple cable replacement is required? Would that be a common thing to go?
    Or is it something else??

      It is very common. Check it this way: Unscrew it at the bottom of the tachometer and place the end where you can see the inner cable. Start the engine and see if it rotates.
      If not, pull the other end and check the inner cable for breaks. While it is out, you can also put the end back in the tach and spin the inner cable by hand to see if the tach needle moves. I have put a variable speed drill on the inner cable before and tried it that way, but you have to be careful to not exceed the speed of the tach.
      Best of luck.

          If you use a variable speed drill to test it, remember the cable spins counterclockwise (or reverse on a drill). Otherwise you will get no reading even if the tach is good.

                  If the inner cable is broken, just replace the whole thing. The concensus on the forum is to use OEM replacement cables wherever possible.

                      Looked at this yesterday..Cable was broke at the engine side, about 30mm into cable.
                      Ordered a new one, so that should sort it. Thanks again!
