I've been working on a microcontroller driven digital LED instrument cluster for the next motorcycle I plan to buy. Mostly this is just paper stuff, I don't have the parts yet to actually build anything.
The gauges all use rectangular LEDs running off 8-bit shift registers chained together for each bar. It allows me to run each gauge completely digitally off a single output on the microcontroller. The Speedometer, odometer, and trip displays are 7 segment displays running off a serial based controller that also lets me use a single output from the main controller for each individual row.
I've also included in the design a solid state turn signal driving circuit, with indicators built in, it's more reliable and lets me use LED turn signals. As well as a solid state relay for the headlight switch, allowing me to run brighter bulbs and high beams.
I really wanted to go for an old school look, like the bar graph dashboards from some 80's cars.

I'm actually a mechanic myself, though currently out of work. I was aware of the neutral points for coolant temp and volts, this was a very quick thrown together mock up. It's just a case of shifting the scales over a bit, admittedly I could have just done that but I was lazy and worked out from the middle with general numbers. >.=.<
I also thought about swapping oil temp for oil pressure, Coolant temp is more than enough to know how hot the engine is running, you've basically given me the final nudge to make the switch ^.=.^.
I've designed this for a CRF250L, a bike I've never even seen yet unfortunately, my experience is with pre 1990 models, mostly air cooled singles or parallel twins.
My current bike is a 1972 Yamaha CS5E, a 200cc parallel twin two-stroke, though it's about to be sold as a project bike, more work than I have money for. Before that I had a 1981 Honda XL125S. I'm kind of a fan of dual sports more than road bikes, and I like them small and light.
