check the battery.Seen similar problems on the FZS600 with a failing batteryHi I thought the same so was one of the first check I carried out around 14V so I assume it ok. was thinking it could be the TPS?

Rotating the TPS records nothing on the speedo 0mph. with the TPS Reconnected and the engine running rotating the TPS does cause some fluctuations in the engine tone but not a great deal. If a TPS goes defective will this cause the Rev counter to stop working?

If you've removed or adjusted the TPS you will now need to rest it as per the manual or you'll start experiencing running and possibly starting issues.If the rev counter and speedo are messing about, check the earth/ground for the instrument cluster as they share the same ones and as also mentioned a failing battery can also cause issues. Failing that but it's unlikely the wheel senor is breaking down and so is the sender on the rev counter but as stated very unlikely they'll both fail at the same time. Go for the ground connection

There's several, take each plug/connector coming out/going into the clock binnacle, check and clean every connector both sides, using the wiring diagram check for continuity on the grounds. It's possible you may have got water ingress into one or more of the plugs/connectors, it may have corroded a pin/s to the point they lose ground.It's also possible if it bad enough that it's corroded away a pin's or blow some of the internal boards, unlikely but possible. If that's the case you'll be looking at replacement, unless you've got the kit, components and know how to repair it.
If the TPS is breaking down it can affect the rev counter. It can randomly misbehave and jump about. It's happened twice on my bike which is why I recognised it so quickly the second time. The perils of buying a used TPS. I never touched or adjusted anything else at the time and the replacement TPS corrected the problem. As mentioned it has nothing to do with the speedo though.Hi thanks for the info, the reason I mentioned the TPS was as I recall the rev counter was working prior to me adjusting it. I've found a few checks i can do to make sure its ok or defective. i.e. resistance checks etc.
Remove the Screen and then remove the plug to the clocks and check it for the dreaded blue green corrosion the , if it is OK there then remove the lift infill panel and check the connectors under the panel also for for the dreaded blue green corrosion

If a TPS fails it will NOT stop the rev counter working end of. If you disconnect the TPS the rev counter will still work fine, if the TPS is faulty and connected it will register on the rev counter by making the needle bounce and then go back to normal operation.Neilr your rev counter stopped working, the TPS route is a blind alley as is the advice not to buy TPS's off ebay, ignore it. If you buy cheap or second hand no matter where's it's bought you run the risk of it failing, it's not an ebay issue, it's a buyer issue .
