Probs with Digital Speedo Suzuki DRZ400E

All,

I was out mustering on the Chook-Chaser the other morning. I was pulled up
waiting for stock to run through a gate, and I revved the bike to keep them
moving. I noticed the speedo(LCD Digital) was acting as a rev-counter.
High revs had me doing over 90kph, and an idle was back to 0kph. It kept
doing this until I put it in gear, and moved off. I havent seen it doing
this again since.

Am I seeing something like an impending failure of voltage regulation, an
impending battery failure, or is there something else? I am a bit at a loss
to see how the speedo could be reflecting engine revs, but then I dont know
how these units convert the mechanical input from the front wheel to an
electronic signal. The bike is the electric start model, and I have ridden
(an obviously started) it a number of times since.

Or should I not worry about it? I didnt note whether the odometer was
counting over as well; I was a bit surprised to see I was doing 95 with my
feet on the ground!

Any thoughts or ideas appreciated.

naa, it'll fail or not regardless of operator concern.

it is most likely that you have a bad connection somewhere twixt speedo and
wheel, translating engine vibration into speed pulses.
