I am thinking I would like to put an electronic tach on the 06 iron head so I don't over rev it. Has anyone done this? I see Ngear has a Lucas one, but at that price it won't happen. A scitsu tach is a couple hundred, but does not look period, but that does not matter to me and I would like to spend less than that.Must be a bunch of different ones available out there. The bikes I have, if they have a tach, it is mechanical so I am not sure when electric tachs entered the market.Thanks.
