SOURCE: my rev counter does not work on my kawasaki er5 1999

The ER5 has got an electronic rev-counter, no cable.

Like the oval rear brake-drums this is another ER5 bugbear, the rec/rec fails, the battery boils and the rev-counter is usually a victim too.
Often on ER5 specific forums there will be someone who repairs the circuit board and sells the repaired units much cheaper than a new one. it's usually a tiny zener-diode that is killed.

SOURCE: I'm having a problem with my yamaha yzf1000

This is a diagnostic code telling you there is a problem with the exup valve and/or servo, cables etc. Take the little cover off the exup valve and check the pulley is rotating about 1/3rd of a turn when the revs hit more than 4000 revs. It might be partially seized or a broken cable or problems with the servo. The mechanical bits are easy to fix.

The rev counter goes from 0 to 7000 revs then back to 0


that is the indication of the exup valve malfunctioning. it tosses the code of 7000 rpm for a few seconds on start up to let you have an indication that there is a problem.

I have a thunderace and the rev counter keeps jumping from 0 t0 7000 revs


7000 rpm is a self diagnostic code that either your exup valve is not being detected or the valve is locked up and not moving. If you put a header on your bike and took over the exup valve servo motor, you are going to have to put it back on. It also changes the mapping of the ECU and will not let it rev to redline when the Exup servo motor is missing.

Gilera dna oil light and also rev counter.


Have you had an oil gauge on the line to check what pressure you are running at? You may want to try running a heavier oil in the engine. If you are running a synthetic oil switch back to ester oil. If this does not remedy the problem then a new oil pump will be the fix

My 1999 R1 rev counter just shoots upto 7000 when on tickover


Its a self diagnostic feature. It is telling you either the TPS is unplugged, the fuel level sensor is unplugged, or the EXUP valve is unplugged or frozen and not moving.
