Just do a search.......xs650 PCV valve fitted into existing breather line seems to the cheapest and easiest solution for a Combat

I have a breather available for a 72 combat. Jim

In Combats the further benefit of removing the oil baffle is one can then remove gear box w/o having to tip engine out the way 1st. If reed valve put in that spot but still fouls AMC box then only half the possible advantage in '72s to me.

Jim, can you send me a pay pal invoice for breather, it will be easier for both of us that way I'm told Thanks Barry

This might be a good time to say i did 800km (500 miles) at the weekend on my recently recommissioned Commando - incl the Comnoz sump plug reed valve breather. 3 days after and not a drop of oil below the bike, usually there would be a number of spots by now. Nice.

Hi Iain,
Was the bike you put a Comstock breather on a Combat? I ask because Jim's Combat breather is located in quite a different location compared to the other breathers.

not really. it is still directly in the crankcase like his sump breather not outside in the timing chest like a stock 850 or timed camshaft breather as on earlier 750's. his sump plug breather or combat breather puts it directly in the crankcase where the source of the pumping originates.

My breather for a Combat case is the same height as the sump plug breather's pickup tube. The sump plug breather pickup tube is about 1 inch forward of the breather hole on the combat case. They both work the same. Jim
