the BGF mount is for a honda or hua sheng engine...
the AGK plate has the holes offset so the HF engine's sprocket lines up with the rear wheel sprocket
you would need the guts of the BGF and the plate from AGK to properly line up a HF engine
Maybe an oversight on my part, but I would assume that folks on this forum have some degree of basic tooling, drill, drill pres, mini mill etc, to custom line the holes.
This is a Mod Shop forum right ?
