My Rapide breather has an alloy sleeve in the pinion. If I wanted to change the timing less than 15 deg (one tooth), what is the best way to press out the sleeve - freeze it first?

Yes, I think so as the alloy will contract much more than the pinion.... go for dry ice if the home freezer doesn't do it. Good luck.... but truthfully I would use one of those add-on breathers over the mag plate on the timing cover.

I believe my hydraulic damper would hit such a non-concours item. What I may really do is get the parts for the two disc friction damper and use my Ducati breather in that position.

Howdy Bruce,

Or leave that nice dampener in place and fit this $5.00 item from Auto Zone. Read about it here.

Actually, a "D" breather isn't so hot either as all the breathing that needs doing is restricted by that little cut-away on the upper guide.

But if you're going to use a D breather, cut a couple of crescent shaped pieces out of that upper guide !!

If you think about it we are speaking of a crankcase breather...... why make it such a torturous route in the first place when one can achieve much more efficient and direct flow with the simple six screw add on AT the crankcase?
