PCV for Hawk
I've seen several people mention installing a PCV on their Hawks but no mention of the part number they used. Auto parts stores are too lazy to match a PCV to hose size.
What PCV do you recommend? Preferably one that same size hose fitting on both sides as I'm keeping the air box for now. |

Positive Crankcase Ventilation. PCV. A PCV on a motorcycle engine reduces air pumping losses. Air pumping takes power that could be otherwise employed. It reduces air pumping losses the same way as as the crankcase vent valve on previous motorcycles. Harley-Davidson uses a rotary valve for this purpose. Ariels used a ball bearing in a cage to do this. The PCV unit is an inexpensive way to get positive crankcase ventilation on an engine that doesn't have one. Like the Hawk. A secondary benefit is less pressure on the seals. Also better engine oiling. And, for pcspecialist, it reduces the oil getting into the air filter element.

What size hose is the hose on the HAWK?
If the size is different than what is on my Bashan... I might be able to find you a few PCVs that work (I'm really good friends with the Manager at an Auto parts store)... but it will have to be on 'our free time', as in, no other customers in the store so we can go PCV hunting
