Anybody have any experience with them? (Multi Functions) I was originally looking for a new temp gauge for the track bike, and I've been contemplating putting a small light up front and a tail/brake light out back so I can take it down the road from time to time and its not just always sitting in the garage except the 4 times or so a year I might get a chance to go to the track so I've been looking for a speedo as well when I came across this stuff.

I got to looking, then I thought.. Now that would look pimp as hell on the VTR

RX-1N SPEEDOMETER / GP STYLE (WHITE FACE)

They can be had much cheaper on flea bay.. but I was curious if anyone had any first hand knowledge, or if I will end up being the Guinea pig if I decide to pull the trigger

Edited to add: Does any body know if the fuel level sender on the newer model fuel tanks will go into the older model fuel tanks where the switch for the low fuel light goes? if I went this route it would be nice to be able to use the fuel gauge instead of just a low fuel light
