    I bought a 1995 sl 650 with a seized engine. Can I put a 750, or a 780 engine on it?

    There are a lot of components that are interchangeable between them. You will want the correct stator and CDI for the new motor. The baseplate on the 780 motor may not be the same, but the mounting holes are and you can swap baseplates with what you currently have. Carbs are interchangeable, except the 780 has them turned 180 degrees, so the throttle and choke connections are on the PTO (rear) end, not the MAG (front). But again, if your intake manifold is in acceptable condition, you can reinstall it on the 780 and use the 650 carbs.

    This is a general list and not all inclusive. The 750 is a pretty even switch, with a few more note worthy items on the 780. You can find either just as easily and priced about the same. I would go for the 780 if you have a choice.
