When I made the read valve, I mustn't have been paying attention, when I took the breather off the rocker box after stripping the motor, I discovered the outlet hole in the rocker box was partially covered, apparently I didn't mill enough out of the valve lower plate, strangling the engine. .So, I remade the lower section.
I milled the inlet slot out to 16mm and the through hole out to 10mm x 20mm. If you've ever tried to tap an M3 thread you'll know it's very frustrating, slow and this time I broke the tap, so, I drilled the petal holes out to 4mm along with the petal limiter and rethreaded the mounting holes to M4, much easier. While I was on the mill I also drilled out the 10mm hole in the outlet spigot to 12mm so it matches the catch can inlet. thread
