Rear Crankcase Engine Oil Breather Valve
 

Wow, what a mouthfull !

Right, my 996 has a plastic one of these that seems to leak a bit, and is really getting on my t!ts.

I have to confess I've not examined it closely, so it could just be the O ring is leaking. Have others suffered from this same leak ?

I have also seen some other bikes with what look like turned alloy ones.
Any ideas on who sells these, and what sort of dosh they cost ?

Cheers,
John.

Mine also leaks...and I've seen loads of others also...I don't worry about it as it seems to be a miniscule amount that actually comes out.

As for the fancy ones, try techmoto or Casoli (if you dare!).

I have an STM one from Tecmoto.LOvely piece of kit and doesn't leak!

Nichols Manufacturing also makes a great replacement unit. The aftermarket units are all pricey but you only buy it once. I've had my Nichols breather on for 5 years and it hasn't leaked a drop since. They also make other very nice components for your Duc.

I have the STM version from Tecmoto and its definitely worth the money. Looks good and no leaks.
