I adopted Darkhelmets method of chain adjustment which works very well to help get the feel of it. Helps if you have a centre stand or axle stands under the footpegs to support the bike with the rear wheel off the ground though.
What you do is take the bolt out of the dogbones to the swingarm, so can move freely up & down, then support the swingarm preferably with a jack. Then raise it until the centre of the front sprocket, swingarm pivot bolt , & rear axle are all in a alignment. Check that the chain has a small amount of play, also turn the wheel checking for tight spots.
It is a bit of a performance so only mainly do it if I've just had the wheel off for a tyre or something & my tools are out all over the floor anyway.
