Change the oil. Check your wheel bearings front and rear, making sure no binding occurs. Check your chain and lube and check chain tensioner. Make sure no debris in the rear brake drum. You may have to remove it and clean it out. Lube your front brake cable if you still have it. Make sure your brake assembly isn't binding and hanging up. Check the adjustment on your clutch. You might want to clean your oil filter screen too if you haven't done that in awhile. Sometime you can take in all kinds of nasty stuff with water in places where you don't want it.
