A couple of reasons actually. Originally I was looking for electronic. I've seen Keith's and his electronic, and seems to be more accurate than my stock one, as well as fairly easy to calibrate.
As I've been looking around it seems I've only been able to find mechanical ones that have the dummy lights and a trip meter. I can then get a matching size tach. I'm looking to change tanks eventually, but I like having all the lights and gauges.
...and of course I just think it cleans up the front end and looks cool.
