All motorcycles work better if you properly set the sag for the rider. Unfortunately it's something you can't do yourself and usually requires two other people to do it right.
I think the dealer should do that when you buy the bike before they let you ride away. The next time I buy a new bike I'll be sure to insist on it.
I've gotten in the habit of letting a professional set the sag for me as part of a charity event held at Helimot in San Jose every December. Somehow that's just easier than doing it myself. And by the way, it seems to take about 20 minutes when done by someone who knows what he's doing, has helpers available, and has all the right tools sitting out and ready to go.
