Tach needle going krazy(Update)

Got an intermitent problem with my tachometer.Needle starts fluctuating for no reason at all.At idle it shows zero , at what I feels like a 5-6K goes all the way to the red line.

I don't know if it maters, oil change done a few days ago.
Bike is 2006 GS500F with a 6.***K.

Any ideas?

Thanks.
Roman.

check the tac wires maybe a loose connection or a short in the electrical?

^^^^^^^^^
+1.
Newer GS's ('04+?) have electrical tachometers. Checking out for bad/loose cable connections is the way to go, IMHO.
I don't think a recent oil change might have any effect on this.
Good luck finding the fault

Is the battery and charging system ok? The electronics in the tacho are very sensitive to under/over-voltage and an erratic tacho can often be the first sign of problems related to the battery and charging sytem.

MrHyde had the same problem with his tach - his charging system was fine, and everything else was good. I had a spare 02+ tach laying around, and after replacing it, everythign was good.

Could just be a bummed tach.

Sorta like the speedo's that go all wonky...

Checked charging system, wires, conectors to the tach and igniter.Everything is OK.
I guess just a gremlin in the tach.F it.Until it start doing it all the time I'll do nothing.

But I still want to know what was going on with the tach.

I just had this same issue on my '04. It only occured about a half hour forty five minutes into the ride. Really freaked me out at first being that I had only had the bike for three weeks and only been riding that long. Long story short it took the shop a while to catch it they said that the tach was fried and replaced it. Gotta love the warranty already paying for itself!

Does this happen to alot of other 500's ?
