I think you'd be the first to integrate a fuel gauge to the S40. It's more complicated than it looks.

If you ride on reserve, it quits and you walk.
Just put gas in about every 100 miles.
It's easy.

The guy I bought my Savage from said he'd been considering drilling two holes in the tank. One near the top, one near the bottom, both on one side of the tank. Then adding some fittings and putting a section of clear fuel line between the two. Then the fuel level could be seen from the outside of the tank.

Personally, I'm glad he never got around to it, and I just refill the tank every two days running back and forth to work. That's a 43 mile round trip, do two and refill. Or, like others have said, refill every 100 miles. About the same.

I have a 1 liter fuel bottle that I use when going out of town.  



Best regards,

pgambr: Excellent idea but 1L is equal to about 1/4 gallon. That's probably about the equivalent of our reserve I would think. Every little bit helps if you don't have to push!
