can anyone tell me why when im steadily cruising at 70mph in 6th gear the speedo needle flicks up between 80-90mph without moving the throttle pedal? its happened more than once, ive not noticed it at low speeds.
Is it anything to be concerned about?

 

Someone must have an answer? and not a sarky 1

 

mine does it aswell, and at low speeds.

looked all over for an answer but I still dont know

 

hey mate mine did do it but its sorted it self out now so leave it it could fix itself

 

Sounds like a possible loose electrical connection somewhere - I had some issues after fitting a speed converter / delimiter chip to mine, turned out to be bad connections, just needed to solder them (block connectors don't work well for this) - that would only apply if it has electronic speedo tho
