A stock CA95 air cleaner has only one small auxiliary-hose hole punched into it. So, if either the crankcase breather or valve guide blowby breather hoses were originally routed into this hole, then that would imply the power jet would've not had access to that hole and thereby had to intake unfiltered air directly into the carb. I just couldn't convince myself that Honda would've approved that as part of their original design, so I researched it further when I was building my '64 (with the '63 motor).
Here is a picture of that 491 original mile Benly (documented original owner was a Shriner) that my friend recently sold and it has a hose coming in from the air filter area into the power jet. It also shows the clear valve guide blowby breather hose exiting into the area down below the carb, as well as the black crankcase breather hose being routed through the carb cover cutout. The second pic shows the crankcase breather hose exiting in a typical under-bike location.
I thought I had this question figured out, but if not, I'm all ears.
