I think you won't get much change out of $600. I did it myself on Gerda's bike, including the steering head bearings and a fork oil change. It's actually not all that hard if you prepare well. I ended up taking the shims out, needlessly as it turned out. I had used the single spark specs on a twin spark bike. You'll find the valves will be fine. Bleeding the coolant was a bit fiddly. The oil has to be drained in two places. The sump plug is a pain in the butt. Other than that there is nothing to it. Servicing is a good way to get to know your bike.Alex
