    1981 gs650E to 750 engine swap

    Hi I just aquired a 81 gs650E chain drive silver bike , but after getting home the engine is done no compression , I looked for a decent used one but the chain drive is in short supply , what years of 750 engine might fit in my frame or is even a 1000 or 1100 possible

    Do a top end rebuild, it's easy if you can turn a wrench and can read.

    Life is too short to ride an L.

      The 650 frame is too small to accept the larger engines

      No compression? like zero psi?

      Since it didn't run, I can only assume you bought it cheap as a project. Cheap means $1,500 to get it running well
