When I had my 650 the fork oil was changed every other winter(20 - 30K) and it was always "very" dirty. Once the tubes were off the bike,caps removed, springs pulled and then the old fluid poured out. Then a few ounces of paint thinner in each. Pump up and down and pour out. Repeat until clean. Now pour in a couple ounces of fluid(Fork or ATF) and pour that out. Now fill and reassemble per your manual. Can be done in 1-2 hrs and super clean.
PS - If you install Rancho boots you'll find the old fluid so much cleaner that you might not need to this for 50K+. I installed them at 100K and at 122 the fluid was barely dirty.
