What Engines Directly Bolt Into A 1982 Suzuki GS650G?

I have a 1982 Suzuki Gs 650G one of the bearings that connects the crankshaft to the piston rod is bad. I tore down the engine to find this out. From what I have heard it is very difficult to fix this problem and I should just get a new donor engine.

So what engines can directly bolt into my bike? Thanks for your time!
 
Any of the shaft-drive 650s will work for sure.

Because of the shaft drive and smaller size, I don't think you would get much else in there. The block is similar to the 750, but the 750 shaft-drive did not make it out of Japan.

If you have a manual, and have already torn down half the motor to find that problem, your half way there. Its really not that tough, just follow the book, and you can probably do it. Otherwise, the only thing that will bolt directly into that frame, is another 650 shaft motor.
 
I don't see why it would be hard to replace the bearing, even if you got a crank from ebay. The engine weighs 208 pounds (ask how I know) and shipped you're looking at 200 dollars plus whatever the engine costs. If you had a busted case or a bolt snapped off somewhere that would be different. But I would call this a repairable offense, you just need to spend the time to work on it.
 
I agree with fixing the engine you have. Good fun.

The chain drive 650 engine was derived from the 550 engine, so maybe you could get a 550 engine to fit the mounts. Going to be way more work than just fixing your 650 engine in the end I suspect.
