How to remove the rear tire with shaft drive

This should help you a fair bit, it's not that big a job.
Instructions below found at:

---------------------------------
In addition to the obvious of elevating the back of the motorcycle to get the weight off the rear tire, you need to unbolt the final drive from the swing arm and remove the final drive and rear wheel as an assembly. The drive shaft will come out with the final drive, not a problem.

Once you get the assembly off the bike, you can remove the axle then separate the final drive from the rear wheel and do what you needed to do.

When you go to re-install the drive shaft, you have to align the splines. Sometimes it is easier to put the bike in gear so the female splines on the intermediate shaft don't turn as you rotate the rear wheel to insert the drive shaft.
When you go to put it back together, just tighten the bolts that hold the final drive to the swing arm evenly in a crossing pattern until tight.

As an aside note, while you have it off, make sure you grease the splines on the end of the drive shaft and the splines for the rear wheel before putting it back together

It is very typical (and intensely annoying) that when you transition from accelerating — however slightly — to decelerating — however slightly — there is a big bounce as if there is enormous slop in the drive train.

Every motorcyle I have ever had (Kawasaki 175 2-stroke, Honda CB350 twin, Yamaha 650 twin, Yamaha 750 special and Suzuki GS 850), and every motorcycle I have ever driven (Honda CB 50, Yamaha Mini-Enduro 60, Honda Hawk 400, Kawasaki 750 LTD, Yamaha Virago 650, Yamaha Virago 750) has had this “feature.”

This site has tyre changing techniques for all manner of tyres, wheels and final drive systems.

jack up the bike at the motor & remove the rubber covering the front of the shaft!
from my recollection there should be a lock bolt under the rubber
rotate shaft to get at it
youll need another person to help as its a fidly job [watch your fingers]
remove rear shocks & pull out the whole rear drive assembly!

The final drive assembly has to be unbolted from the swingarm and it is removed with the rear wheel. Once the assembly is off the bike, the axle can be removed and the final drive separated from the wheel.
