Looks like a drain/fill multiple times procedure. How often should this be performed?
I've got water/water wetter solution that I had put in bike early this calendar year. Bike sat for almost 3 months during summer. Since the overflow bottle looks pretty good, shouldn't I also expect the system to be pretty clean?

 

Did the flush today. And what should come out of the cooling system???? Green, sweet-smelling anti-freeze. I shouldn't have to feel like I have to check behind the dealership who did the work AND charged me 0.6 hrs labor ($48).

Iused Abad's procedure from the "other" cbr site and modified a little. I ran the bike between fillings with distilled H^2O and drained until I was satisfied that I got 98%+ of the green stuff out.

I guess I will flush again mid 2008, although its suitable for annual changes.
