Welcome Jim to the brotherhood of the speedo.
I am used to mine now, all the people who told me to go buy a Harley as that's what I was trying to do with my bike all now agree it looks way better.
I bought the LED version (2856 Model) but you cant run tank console lights and the LED warning lights at the same time cause you risk blowing the speedo due to the amount of power the neutral pulls (or so i was told).
Had the LED lights and they were useless, so went back to tank lights.
Haven't had any problems with the tacho, but as the speedmaster has a tacho it was just a case of using the exisiting wire - can take photo if anyone wants
