If I'm betting on my (admittedly very dated) experience, this thing's got a 305 smog motor that's never had the heads off, a dual exhaust done at the local muffler shop, and way too much carb, possibly on the factory manifold. All bark and no bite.
This is the four-wheeled equivalent of a KZ650 with an unpainted fiberglass bikini fairing, factory suspension, a no-name 4-into-1, and intact chicken strips.
