I did this all by my lonesome, except for borrowing my hubby to help me get the tank off since I didn't want to drop it or anything, and I did that, an oil change, detailing, and lubing the chain in an afternoon, and that was with a stop to get oil and another stop for the filter... Not a bad project at all.... I'd say maybe a 5 only because it's easy to lose things like fasteners if you're not careful....
Radio Shack has a great deal on washers in this pack:
