Dodgy Clocks
 

A wee search shows plenty of folk with speedo issues caused at the front wheel, but what about the bike lying altogther and showing the wrong revs as well?

I was following a long line of traffic this morning, tailed by a Fiat Punto, on the motorway at 109 mph, and about 7.5-8k revs, I reckon I was doing 75-90 mph max.

The traffic congested a bit (to about 50mph I reckon which is about normal for that time in the morning at that junction), but speedo and revs were still showing 75mph and 5.5K revs, which correlate to each other spot on as I remember that from the running in period.

Anybody seen this b4? Wrong speedo and rev counter, but the two agree perfectly in 6th gear. I have an 06 pointy. Ticking over stataionary revs show 1.5k and speedo zero. It's working fine, but just all just gone a bit optimistic. Thanks

When I had a dodgy battery the speedo went nuts and showed I was doing 184mph! Prob not the same thing but it's a possibility. I'd get back to the dealer if it carries on.

I've had similar, but only in a car.

In my case, it started by the rev counter & speedo "sticking." You could speed up, everything was normal, slow down, and it'd stay there for a few seconds then think to itself "Oops, we've slowed, maybe I should move now."

Over the next few days or so this carried on, then one day on the way home, all hell broke loose. Rev counter up & down (if it could of, it'd of jumped up & ran around the inside of the car), speedo doing the same. WTF?!?!

At one point, I was apparently doing 2k rpm, 190mph ish, in a 2.0l Ford Galaxy. Erm...

After a while, I'd pretty much made my mind up that it was an alternator fault giving the wrong voltage back to the rest of the car. A few miles later down the road, battery light on, all dials back to normal operation. AHA!

Ford Galaxy's have expensive alternators :(

Check the battery connections and starter motor relay connections are tight.
