This will allow air into the crankcase at low revs when there is negative pressure, maintained by the PCV and as crankcase pressure builds up with the revs and the PCV shuts, the pressure is released into the air filter body and passes through the combustion process.

Hope this helps.

I ran mine in that configuration in the beginning and it created too much vacuum/smoke/sucked the oil out of the rocker covers. Now changed to PCV plumbed into the carb full vac port.And the other Rocker Cover breather open to Air. Works for me :thumb:
