    '82 650GL project bike, crankcase, and GL to G conversion

    Hi ever'body,
    I'm new to this forum and this model of bike. I've just been given an '82 GS650GL\\/. Downside, it doesn't run! The last owner put in the oil filter backwards:shock: and, well the engine fried. Which leads me to a couple of questions:

    1) I'd like to keep the VIN # of the original engine. When I purchase the other engine, could I mate the top half of the original crankcase with the rest of the "new" engine without creating a new slough of problems?

    2) Anyone know where to obtain a good functioning, reasonably priced engine?

    3) While the GL version is classic, I particularly like the GS650G version (e.g., see: http://www.hoohoohoblin.com/SuzukiGS650G.html ). Is replacing the bodywork of the GL w/the G feasable? I suppose if the frames are the same, it would be. If this is feasable, pls disregard #1 above.

    4) The mags are really nice. I'd like to put some tubeless tires on these rims. Anyone know if that conversion is possible?

    I look forward to riding the GS in whatever form it turns out, and thanks for the help!

    You shouldn't mix and match split crank cases. They are made to match. Is the old engine froze?

      Cutting off the numbers from one engine and grafting it onto another would be not only highly difficult, but completely illegal.

        Yes, the crank is frozen. The match issue is the one I was concerned about.
        I haven't split the cases yet, but sans the heads/sleeves looking down into the case, the crank is completely immobile.
        Looks like I need a new engine?

              Sorry, I had a little too much whiskey before posting last night.

                Hey CJ,
                No harm, no foul. I hope it was good whiskey, though!

                  Do you have a roller bearing crank?

                    Shaft drive 650's are plain bearing.

                    Engine might be salvageable. Only way to know is to take it apart.

                      If you seized a rod and did not gouge the cylinders I'd say you can reuse it. If you burned the crank bearing journals I'd say junk it while possibly using the top end.

                        I'll open the case and take a look. Thanks for the input!
