So there is NO drilling the stock tank.
Petcock stays open ALL the time.
Both tanks vent using a shared vent hose coming out of the TT tank.

In theory, it sounds like it would work! And you stated you've done this using a jerry can for many miles.
As long as you have an airtight tank, the fuel pump should provide the fuel suction to draw all the fuel to the engine.
Sounds like you have to have the "canisterectomy" done too (US bikes only).

Sounds awesome!
In about a month, I'm gonna try this and will report back with pics!

Until then.


Friend of me did this on his F800GS and this works perfect! Bought the TT tank myself some months ago, installed it the same way and it works splendid (after having some minor problems in the beginning).

You don't need a fuel pump to get the other 2.5 gal ...
