    Anyone ever had a problem with a stuck rev counter needle?
    mine seems to now think 3.5k is 0 and wont go below that even with the ignition off it stays at 3.5k and when revving now goes off the clocks before hitting the limiter blue lights come in at the right time though.
    Spoke to webbs triumph they said they would just change the clocks at a whopping £800!!!!!
    Anyone got a set for the early model 2006?
    Thanks for any help.
     
  2. £800 for new clocks???? WTF???
     
  3. Mind did that when my Reg/Rec was starting to go, but it thought 5,000rpm was 0. My digital speedo stopped working too but Jack Lilley replaced it under warranty thankfully.

    Do you have access to TuneECU...

    You can run a test on the clocks that also has the effect of resetting them to 0.

    (at least it did to mine, when they got stuck around 4k when i hit the kill switch when the clocks were doing there startup movement).

    Second hand clocks are loads cheaper on eBay. One 7or 8mm bolt on the back and a plug. If you get a replacement can I have a button please as I've lost one :grin:

    hmmmm when i noticed i stopped and the bike cut out still has old reg/rec checked the charging the other day and all seemed fine though.

    After a few start up's it has gone back to normal so sorry chris the clocks are staying on for the moment.
     
  7. My older Daytona while riding along , would jump up 4,000rpm. It would contantly over-read 4,000 however you varied the throttle, but you could make sense of it.

    Simply switching the ignition off for more than a few seconds seemed to cure it, but not if you quickly switched off, then instantly back on. It happened a few times last summer, but has never resurface yet! I am not sure if leaving the m/c outside in the rain all weekend at rallies had anything to do with it.

    I've travelled 4,000 miles since those problems, with a trip to Sweden and then a trip to Netherlands, and had no trouble since (except replacing the wheelbearings at 30,000 miles for an MoT failure).
     
  8. a little trick if you want totally clear the bikes electrical system of voltage/current is when it is turned off, hold the horn down for like 5 seconds as it drains whats left to ground. i had to keep doing this for my HM Dash when it was playing up and it cured it until the screen just died.
