Hi, Anonymous oil leaking from your air cleaner or breather is caused by oil carryover from the engine. For whatever reason, the breather system is not separating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more expensive ones. First, make sure your breather hoses are not dry-cracked-pinched if they are ok you can start by trying the following:
1. Run your oil level halfway between the add and full mark when hot.
2. Run oil breather lines from the head into a TEE fitting be low carb/induction module then a single line into a mini-filter or PVC valve under the frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump.
5. Replace piston rings and follow proper driving seating procedures
6. Upgrade the oil pump and cam plate.
