This video starts with me removing the primary side exhaust pipe more for clarity than ease of doing the job, with the exhaust off I show how to check for a worn chain in this case both the chain and rear sprocket are extremely worn I certainly got my monies worth from them, ideally both gearbox and rear wheel sprockets should be changed together but over the years I have found I can wear out two rear sprockets on one engine sprocket and over these I would wear out around four chains, the easiest way to check for wear is by pulling the chain away from the sprocket any gap that is seen between the teeth and the chain points to a wear, also the condition of the teeth on the sprocket should be flat at the tips and not pointy or hooked also the teeth should look the same on the front and rear faces. As a tight spot on a used chain is pretty common any adjustment of the chain should be done with the tight part at the bottom and gauge the lift from this position. Then I go on to remove the wheel, first everything is slackened off the chain adjusters the brake stay the brake rod and then the spindle also the speedo cable is disconnected, with everything slackened I then remove the split link and the brake stay this allows the brake plate to be turned and the brake rod can be removed, then knock out the spindle and the wheel can be removed. With the wheel out of the bike I then give the frame a good clean with oily petrol and grease the swinging arm.

After a quick check of the swinging arm bushes, I set the wheel down on an old tyre and remove the sprocket then clean off road dirt and old lube then check the spokes. I then check the wear on the sprocket and compare it with the new one then fit the new sprocket to the wheel after lubricating the bolts; I then do a rough balance of the wheel as the chain and brake plate are not fitted using the swinging arm as the support I got away using a proper balance weight if any extra is needed I would cut a strip of lead and wrap it around the correct spoke.
