Hi Anonymous, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck
