Kawaski is really proud of their gaskets/seals. I needed to drop an oil pan and decided to change all the rubber rings down there "as long as I was there". I sent a friend to the dealer to pick up everything I had listed from the manual. I was very surprised to see over $100 on the receipt. Other than ordering from Murph's, Ron Ayres or Bike Bandit, I really have not found a way to save much money.
