what's the best additive for the coolant system.... or just go 50/50 with good ol green stuff?

 

Coolant: Drain, Fill with Distilled, run bike, repeat until clear. Fill with Honda stuff. If you like the track, go Distilled and Redline water wetter.

Forks: It's more than a drain/fill. There's fluid inside the cartridges, etc. It's more like disassemble, check shims, clean, reassemble, add fluid to the PROPER level.
