Made the mistake of visiting HD store last eve. and was shown new speedometer/tach combo now available for '04 + Dyna. It is typical tach face w/ digital speed reading and is a plug and play so no having to fool with wiring to install. Capable of giving fuel consumption, gear selection, plus color selection of read outs. Dealer just got one in stock and upon examining appears to be of quality and does look like a serious instrument. Been considering adding a separate tach for the bike, but held off for not wanting anymore clutter on the bars, but all in one does the job. I have always shifted according to speed/sound and not considered tach necessary but believe this may be a nice addition. Running JIMS120 and always curious as to the rpm's vs speed so now I will be able to find out. List price near 300.00 and like I said, made a mistake going down there.
