What voltmeter is that, and how is it mounted? I like that better than any I've seen so far! Very nice bike! You should have no problem selling her!
It's a voltmeter that I got from JC Whitney a few years back. Looking at the current JCW website, I see they no longer appear to carry it.
The "enclosure" that it's in is no more than a spray can lid painted silver and sealed/glued on with silicone sealant. The mount is a chrome plated bezel designed to go under a car's dash. I just turned it upside down and used some automotive body-trim grade double-sided tape to stick it to the instrument cluster.
The marine meter tip may be your best bet. Somewhere like http://www.westmarine.com
Thanks for the kind words.......... Roger
