I posted this on the Champion board but thought others may want to see the changes.
I ran it almost out of fuel and took all but 1 battery out to save weight.
Here a few of the Tandem Trailer conversion, as well as new cowlings and some other upgrades.
I cant take all the credit I'm not a master welder, but everything else i did do.
The old EFi is still under there, just upgraded the cowl and pans.
