Crankcase Breather


Cuts Oil Leaks and Reduces Engine Wear, as it
Flushes Toxic Blowby from your Crankcase &
Rockerbox.
Engine power may be enhanced on some bikes, as
crankcase air pressure, downforce work-loads and
drag reduce.

Noted Classic engineer and Norton racer Peter
Williams says, in his June 2005 Classic Bike
review of engine breathing..."...leaked blow-by gas
is nasty, obnoxious, and corrosive stuff
and it is best to have as little as possible in the
crankcase..." Blowby occurs every time we ride.

It forms a corrosive, flammable mixture, that eats
away at our engines, if left inside. Blowby is ~70%
fuel, water, sulphur dioxide, nitrogen oxides, soot
and ash. It's like a concentrated acid rain.
