Question about 1982 Yamaha XJ 650
Looking at putting a 650 turbo motor into an off-road buggy and was wondering if anyone has heard of a conversion to run a chain out of the shaft drive gearbox, or if the rear axle assy is able to be converted into some type of diff arrangement ?
I would like to put a 850 su,motor on grizzly frame.would it work?

Changing this to chain drive will require some significant expense, you may need to even change the output shaft of the transmission along with multiple case covers. You may be better off running the drive shaft to a differential. I'd suggest looking into some of the newer ATV's that run a differential and perhaps adapt one of them to your application.
The drive shaft sort of limits your ability to adjust the gearing as compared to the chain drive. You may be smarter to find a used Yamaha XS 650 engine and swap all the parts you need out of it to your turbo engine.
On another note, I used to race an OW31 Factory Works Yamaha 750 which was essentially the same basic engine that you are installing the turbo on and I'd like to caution you on cam chains. These baby's eat cam chains if you put more than 100 hp out of them. Dropping a cam chain can be VERY costly, you most likely will destroy pistons, valves, and even bend connecting rods. So if your going to put massive power out of this great little engine make sure you change the cam chain at least before you run it with the turbo. I have seen first hand what carnage happens when you lose the chain.
Best of luck and let me know if you need further assistance.
