My bro was riding my 06 on a 180 mile road trip and about 20 miles from his destination thought he felt a hickup. He noticed a few minutes later the tach read 12k rpm's. The motor was running the usual 7,000 but the tach is now off. It idles @ 7k on the tach now. He thinks it lost about 5 hp as well. He will have it back to me tomorrow but i was looking for a little guidance as to anyone else having this problem or where to begin troubleshooting the green monster. FYI the bike has 2500 miles on it and i am the orig owner. The oil was changed at 100, 200, 500, 1k and 2100 miles

TIA

Isn't the tach on the '06 electric? Mine is fed by an electric impulse through a wire in the harness. In fact I used the OEM tach wire to power the digital tach in my Trail Tech Vapor instrument panel. The speedo on the '06 is cable driven, but I think everything in the tach, even the analog gauge, is electrically driven.

I would say that the tach issue is just an electrical failure at the tach or the tach wire is shorting, but with the possible associated performance issue that seems to have occurred at the same time, perhaps there's a bigger electrical ignition issue going on. Hard to say based on the limited info.

 

Got it home today and good news. Power is all there. I think the tach is some kind of cable driven(havn't look it it) as it is sitting at 7k when the key is off. I am confussed why it shouldn't be at 0 if the key is off if it's an electrical signal.

My '06 tach was electric signal to the gage readout. Not sure what drives the signal...

 

If there is no power to the gauge, try pulling the needle off, and re-setting it at zero. It almost sounds like the needle slipped on its pin.
