Regular shops don't have the proper bleeding machine hat is apparently absolutely required. So I asked some local Ohlins Service centers, and they couldnt handle it due to needing special tools (typical ohlins!). So I sent it to Ohlins USA in North Carolina. They turned it around the day after they received it, really awesome service. Needed new o-rings and a new vane. And of course new fluid.
Yes, it was new.
Actually, desert riding can be pretty harsh, so ?
I have no idea, but Ohlins did say every 100hours, and the suspension was definitely due. So I figured I'd do it at the same time. My local guy will do the suspension.
