Curious if anyone else has ever seen this problem.
My battery is on it's last legs and I had to jp start the bike to get it running this spring. Also if I don't rev it while stopped it will die.

However I noticed while revving it in neutral the oil light was flickering and the speedometer was revving with the tac. I'm in neutral at a light and revving away to around 3000 rpm and the speedo is jumping up to 80 km/hr. Also the oil light is flickering red.

But then when I start riding it just works fine.

Is this because the electronics are all messed up with the dead battery? Anyone else ever seen this?

Yes more than likely the battery causing your other issues. Bikes today like a nice strong 12V supply of power, just as todays cars require it.

I agree. Don't mess around with a duff battery. Get rid of it.

So I ordered a Lithium battery (Braille G5). The bike now sounds like it wants to start but just makes a loud clicking sound but there is nothing else. I may do another post on this forum and do some searching around..... hope I didn't fry anything by jump starting off my car.

Looking on some other posts - it may be the relay that is shot. I will do some searching to see if there are any instructions on how to replace a relay.

Worth checking out your solenoid starter, clicking usually comes from this when the battery is low could be a bad unit!

Just did a load test with a multimeter. The battery seems pretty strong. It is at 13v with no load and dips to 12.5v when the ignition is turned (light is on). Hitting the start button makes the clicking sound (not sure where that is coming from) and the bike does not start. The battery voltage stays the same and does not drop below 12v.

I'll start googling how to check the solenoid starter. Maybe it got affected by jump starting from my car...?
