Just wondering if many many people out there have oil pressure gauges fitted to their bikes or are they a waste of time theses days. I like the idea of one just to keep a check on things but is it a waste of money and get in the way on a dyna.

Street glide has a built in one, keep an eye on it all the time

if you have an efi bike Powervision can tell you basically everything besides what you have for breakfast via guages.

I'll probably go the Arlen Ness, they seem to get the best write up.
