You could try this:
Bypass the Crankcase Oll Breather Hose to AirBox with a Filter and Cap the AirBox Inlet.

Also, you may have a Bad Crankcase Seal:

Excess Blowby from crankcase breather, onto air filter

In my case I fixed the excess oil blowby from the crankcase by replacing "shaft seal ring 12x20x5B " part # 0760122050
avilable from munns racing online
it is located in the alternator cover and seals the Crankshaft Balancer .
if you do it you may want to order a new alternator cover gasket also

evidently the crankcase pressure is metered and vents through the crank balancer shaft .
If the seal is shot it blows major oil for some reason
mine was rock hard and shrunken . It was blowing oil everywhere , especially when doing over 90 mph sustained
