How far will the res. tank go? Like how many miles till it is empty.

 

I've only had to switch it over to reserve once, when I was trying to drain the tank to empty to check the fuel capacity. On an '05 Ninja 500R that gets between 50 and 60 mpg I got at least 20 miles out of the reserve tank. Don't know how much further it would have held out. Hope this helps.

 

Thanks yes it did.
