Those mileage interval dealer services are the biggest rip off ever! They give you a list of all these things they supposedly check but in most cases they change three holes and out the door. What you pay $250 for can be done yourself for about $60. The biggest advantage of doing it yourself is you know its done correctly, you learn something every time, and you get to know your bike. You can easily and should check bolts, electrical connections, tires, belt tension, lights, etc. Best of all, its fun and satisfying!!!
