[Dukedesmo]

With regards to a spinning pushrod, I have an 'Evoluzione Cyclesports' master cylinder on my 916 and this has a bearing in the actuating piston, the claim being that if the pushrod were to spin it wouldn't 'drill' the master cylinder.

I can't vouch for the claim because AFAIK the rod's never spun? but the cylinder has been fitted for almost 20 years without any bother whatsoever, it gives a decent weight reduction and is the only master cylinder I have seen where the clutch fluid doesn't discolour - I have an Oberon on the Monster which also works fine but the clutch fluid goes black after a few hundred miles as do the original Ducati parts.

Unfortunately Evoluzione, a US based company are no longer trading.
