Block off plates

[Lord Popgun]

There is a hose at the rear air cleaner housing that goes to the PAIR control solenoid valve. From there the air goes out 2 hoses to the reed valves and from there down a tube or port (Pics of head look like a cast port to me and no hose is shown on the part listing or service manual) to the exhaust side of the exhaust valve.

If you really need to know how the port is down, take off a reed cover and assm and look.

For Crankcase breathing, the gasses in the valve cover go out a big hose at the back/top/middle of the cover, through a hose to the front air cleaner housing.

PM me your email address and I can send you a pic of the manual drawings.
