I decided to go this way.I guess it’s a spring inside it right?
Beauty of the reed valves is they‘re designed for that rapid and constant movement.
The spring may not be…
I like that idea.I had a valve a lot like that for a while. Eventually it got all clogged up with white emulsified oil. Then I removed it and went back to my stock breathing system (MKIII) which just has a hose connected to the oil tank. The trouble is if the valve is not right on or in the engine in cooler weather it won't get warm enough to steam off the moisture. It might work better if your riding is only on hot days. I plan eventually on installing a similar valve right inside the timing cover. I think with the heat in there it will work better.
That's a lot of money and I plan to have the check valve mod done. Why in the hell Norton didn't include a drain back valve is beyond me. Harley Davidson had them in the 1930s.On your bike you get much closer to the engine, or the source of crankcase pressure than this:
Reed Breather Kit
The Norton twin cylinder engine creates a serious amount of pressure in the crankcase as the motor spins. Over the years the factory attempted several methods to reduce this pressure – from a timed breather off the end of the cam on earlier motors, to a crude straight pipe from the timing chest onnycnorton.com
Is this a common problem with the XS Reed valve?I had a valve a lot like that for a while. Eventually it got all clogged up with white emulsified oil.

How did you mount it?Yup.
Mines the same , used i believe on the Yam XS 650
Works a treat, all but stopped a head gasket dripping on the exhaust
