Just efficient Dave !

Back when I had the 2.7 gal tank , I put one of these in a soft tail-bag mounted on the luggage rack so it was invisible to see, then "T" into the fuel line with it , (yes ) through a in-line shut-off . Well the tail-bag wasn't invisible !

I found a bunch of sizes of them on Ebay .
If I ever have to Ride through Canada I might put it on whatever bike I'm taking ?

We were waiting on a Fairy Boat ride one time and stopped to eat near the loading ramp.
In the parking lot there was a DR650 with a fuel tank that reached down past the motor and really wide ... it was HUGE !
When we went it ... I couldn't help but as "Who's Gas Tank ?"

The owner was used to it

I forgot if he said 11 gallons or 13 gallons ? Anything over 10 makes my jaw drop and boggles my mind ???
