I fitted two of these to different bikes a couple of years ago. On the GS, I had to fit a hood to shield the readout as the normal daylight washed out the contrast and the LED display just isn't bright enough. Even with the hood it's not great, and I'll be replacing it with a more conventional dial-type VM.Time For The Voltmeter.
Picked up the peanut gauge voltmeter awhile back and decided it was time to mount it. Not sure I'm happy with it... we'll see after the other gauges are mounted.
On the XJ, the gauge sits down inside the front left of the cockpit fairing and is much better, but only just acceptable.
