It's fine. Mine was ridden 3037 miles with the spring unhooked. It just makes your clutch feel a little mushy. Most dealers do a good job, but the bikes come from the factory with very little grease. The first thing I do when I get a new bike is check everything, and grease everything. It may sound extreme, but a few hours spent early on can save a lot of time down the road. Upgrade to an o-ring chain as soon as you can.
