    So I just picked up a fixer upper from a guy up in PA. He says he left it outside for 4 months, I heard these engines were mostly Aluminium so it shouldn't be a problem right? The rest of the bike isn't to good. There are some spots here and there on the engine like the clutch rod and the head nuts and the clutch and magneto cover screws are rusted but it should still fire up right? Don't be afraid to be blunt, is it worth trying to fix or not?

    its proly OK. take the carb apart and get all the crud out. make sure the intake and exhaust ports are clean. il bet it will still fire up.

    Of course it's worth a few hours of investigating!

    For a messy, stinky option... if you can swing it...

    diesel it...

    Squirt or dab diesel fuel on all the rusty spots and places... let it set for a few days before messing with those screws, bolts, and nuts. Diesel will seep into any kinda crack.

    Yah, gotta clean out the carb and tank... get some lube oil or some of that diesel into the cylinder before turning the motor over.

    Let it set for a few days...

    Then you can try to fire it up and see what you got.

    EZ enough to clean the diesel off, after you get it running...
    Good luck

    Dump some oil in the cylinder and give it a go! Make sure the carb slide is free and moving (I had to sand the corrosion off of one that had been sitting outside a year or so...)
