Engine Swap?

[popejoeii]

Long time reader, first time caller. Thanks to all for all the good information in the past.


But anyway, I have an 81 GS650. It has a blown motor. Conveniently enough, I have a motor from a 97 Ninja zx6R laying around. I think it would make a nice sleeper if I could mate them up. Do you guys think I would have to do anything major besides get some motor mounts fabricated? Maybe I am completely out of my tree here, so let me know.

Thanks,
Joe

the ZX6-r is going to be highly dependant on having the airbox on the motor to run right. And if you have a GS650G... the swap is next to imposable. If you have a GS650E, you'll need to offset the engine to the right due to the sprocket offset for hte wider tire on the ninja.

It won't be an easy swap.

Even if you could make it fit the chassis on the 650 isn't up to the task.

I think you have upper frame rails where the carbs and airbox are on the ZX motor...
