I got mine at the Army surplus.
paid $4.00 for a metal canteen.
$1.00 at lowes for a brass hose connector,
had some JBWeld and now have a perfect overflow bottle
for $5.00 total.
It fits real good in that little circle under the seat where the air filter use to live.
Had a water bottle, but I'm always on a quest to make it better, cheaper...
