If you have the OWNERS manual, just look in it and find the maintenance schedule. Do everything on it. Including the valves. However, if the bike is in good condition, I wouldn't remove the swing arm or front forks. That kind of thing can be done during non riding season if it needs to be done. I put 128,000 miles on a Kawasaki 750 over 17 years, and never had the swing arm, steering head, or forks apart. Change the oil every 1000 miles. Super easy, doesn't hold much and there is no filter to deal with.
While your riding season is just beginning, mine is about over. I live in Phoenix, AZ, and it is just too hot to ride here in the summer. It was 95 degrees today. Fortunately I was able to get quite a bit of riding in during the winter.
