Have you aftermarket dials in place? Sounds like a fauly spindle behind the tacho...

no all standard

Loose connection I'd guess...

Doing a bit of searching, and apparently the rev counter takes its information from the Ignition Failure Sensor. Just looking to see where thats at...

There was a pic with this post on the ftooc, but the link no longer works unfortunately... how to swap in a new IFS.

dead easy to swap over, just take off the air intake pipe (2 jubilee clips)

The IFS is held there with 2 10mm (iirc) bolts, take off the connecter, whis the only hard part (funny clip thingy), put the capacitor thingy back, then the ifs, put the air intake pipe back on, (remember the little hose that goes to the top of the engine), and done.

Here's what it looks like:

It shows you how to test it on p248 of the 1st workshop manual pdf.

Check for loose wires and/or frayed wires.
