Just had mine installed today. It's the 4" model(Dynas) and due to year of my bike, '05, all the possible functions of the instrument does not work/apply. No gear indicator and no fuel/mileage remaining read out. I believe from '07 forward all of these functions would work. Mine will give fuel in tank reading, rpm, speed, trip mileage readout, color selection for back light but believe that's it. My primary reason for going with it was to have the tach read out. Have not picked up the bike yet, going after it in the morning, and was told you have to put believe 32 miles on it for the instrument to "set??" My set up with the JIMS120 seems to really "light up" from what I am guessing is somewhere near 3000rpm, but won't take me a little while riding tomorrow to see just where the power band is on it. It is a good looking unit and to me expensive, but it's on there now.
Additonal info: Well, went and got box/papers and unit also has a clock and the color selection is wide: red, amber/orange, yellow,yellow green, green, green/blue, blue, blue/violet, violet, pink, red shade, white, what more could you ask!!(think I will avoid the pink lighting, must be for girls bikes)
2008 /Dynas have all functions available except range/miles to go. 2009 -2011 Dynas have all functions available. It would appear that the dealer is to download miles on bike when installed and has tamper proof system so as to not be able to alter true mileage on the bike.
Finally a digital speedometer with a analog tach. combo including fuel consumption , gear counter & all the other pertinent info .
But why take up so much space with an 8000 RPM tach. when it should be a 6000 maybe 7000 RPM at the max ? I mean WTF is that all about ? Who's got a Dyna that'll rev to eight grand ? Why not go ahead & install a 200 MPH speedometer while your at it ! All the poser's out there will surely go for that .
Simple fact you want your instruments to indicate at mid range for normal conditions.
If you expect to spend time at 50 psig then you want a 0-100 psi gauge
If you expect to run 250 degrees you want a 0-500 degree thermometer.
I see nothing wrong with a 120 MPH Speedometer if someone has calculated 60 MPH as optimum cruise, although mine should be 140 MPH maybe even 160. If you intend to spend a lot of time at 100 MPH then by all means a 200 MPH speedometer is right for you.
I do most of my shifting at 4K when winding up so see nothing wrong with a 8K Tachometer.
Digital instruments are not immune to the problems of operating on either end of their scale, they simply provide more accurate indication than analog throughout their useful range.
Shift lights have been common in drag racing for decades. The only purpose for the Tach in my brother's Super Gas is rev limiting and to show max RPM AFTER everything is said and done.
As far as "squeezing" the numbers in only away around that is to make a 7K tach with the same dial face size as a 8K which once again takes up the space you where worried about.
Instrumentation is designed for use in the mid range so if you shift at 3500 RPM then get a 7K tach. That's just the way it is do otherwise and you run the risk of getting a "fast or slow" reading over time.
Sounds to me you don't need a Tach at all just get and setup a shift light.
