Bike does not smoke...noticed oil level was going down very fast...figured out when I rev it past a certain point...not very high...that oil is being blown out at a high rate from the tube at the top of the head. Any ideas appreciate...valve guides? Bike seems to run well...maybe some power loss at high rpm?

I know that if you overfill the excess oil will come out the breather.

I'm putting in a liter without changing the filter (50cc too much) and I'm still not getting any excess out the breather.
