There are usually instructions of how to bond or lift the bond in the installation book.

It is probably not the worst of sins to have it bonded on both ends but it is a 250.6 violation, sharing circuit current on the EGC.

As far as I know Honda generators are the only ones that come without the bond ... but that is old info.

Personally I am not sure why you bond a truly portable generator. Without a ground rod, what are you bonding?
