The seat came from Zomby Builder. THANK YOU ZOMBY! The tank is salvaged from MOOP1. I used this stuff called water weld I got from Auto Zone to seal up that marine grade cap set up. Then I got a second cap because I had to vent the original cap because it won't run when your tank is sealed.

Another mod that carried over from MOOP1 is my clutch mod. Easy clutch pull. No worries about broken cables.I found an old clamp that worked as a cable holder to the frame.

My Boost Bottle is upright on purpose. Apparently it needs to be this way. Sure it would look better mounted horizontally but I think this adds a kind of a "mod old" look to it.
