I've never changed it..perhaps my mechanic did it when the clutches were rebuilt?..... last one perhaps 30k miles ago...and yes it looks a little bit dirty with a some rubber dust floating in it.
I think I'd go for more stainless lines. For now it's topped up and works fine.
BTW, do I need a bleeder machine or can I just use a plastic hose and siphon it into a jar with some brake fluid in it?
Jay, check out the RAT Raid at The Hub next April. Has it been a year since we last rode together? Have to do it again to get push mtn in the past.
