I did a search to find an alignment procedure. Got really confused, laser light? string? Finally went with the Singh low tech method, ride the bike on level ground and take your hands off the bars and see if it goes straight.
The chain play should be set with wheels on the ground and the 180lb guy in the saddle. If you adjust it on the center stand, it will be very tight when you are riding and this puts excessive strain on the chain and sprockets.
