Feuling External Breather Kit For Harley

In house testing, at Feuling shows venting the air cleaner to atmosphere may be problematic resulting in oil carry over/misting out of the breathers. When air filter venting is accompanied with the use of oil tank venting such as the Feuling vented dipstick and or a vented transmission top cover the oil carry over/misting can be increased. The overall health of the engine including the internal cylinder head breathers, oiling system and piston ring/cylinder seal play a major role with oil blow by, carry over and misting out of the breathers. Feulings testing shows the M-Eight engine has limited internal vacuum and the cylinder head breathers prefers the vacuum pull of the intake.
