I have a grizz and compared to working on a car/truck these things are tinker toys. I wouldn't go cheap on the parts if your tearing it down, but dh1984 is dead on, the dealership will rip you big time. Insane what they charge for things like rear brake pads, as much or more than a car/truck and not much bigger than a silver dollar. I'd buy from an online after market dealer, some on ebay.
Good parts, 500 or less.
Like to rebuild mine some day and plan on doing it up right so I never have to do it again.
