It doesn't slowly loose power like a normal vehicle does when you max it out with a gradual decline of acceleration, it pulls until the governor kicks in. I used to drive over the road tractor trailers for Warner and the trucks were governed at 70 MPH. This feels exactly the same. So either: the school system installed some speed limiting governor that was not properly disconnected when I purchased the bus, or: they turned the mechanical engine governor down to some lower RPM setting and I'm not getting full revs. I've ordered a tach so hopefully it can shed some light.
