This is possible with some minor modifications to the bike's frame.
Should fit no problem, ought to be the same engine that was used in the 85s
Yes
I've never worked with a blockhead motor, but I'd think so, because as far as I know the only thing that's changed with Harley engines in the last 30-40 years is the top end.
no a 250r motor will not fit in a 200x frame but it will fit in a 250r frame
No they will not, the frame is constructed slightly differently, thus it will not line up correctly
yes, but the dash, door panels, and electronics will be different
Yes, a 1994 Ford F-350 cab can fit on a 1984 F-350 frame, but there are some considerations. The mounting points for the cab may differ, requiring modifications to ensure a proper fit. Additionally, the wiring and other components may need adjustments to be compatible with each other. Overall, while it is feasible, it will involve some custom work.
Yes it should fit the frame not sure if tank will fit as the 91 barrel and head are bigger
Yes, but you will need do some fabrication to the frame in order to fit it in correctly.
Size wise, it would fit, however it wont bolt into the frame if that is what you are asking.
no frame will fit a nova as it's a unibody.
