Breather Tube Oil
Collector
Keeps the filter for the breather
hose from getting oil soaked by oil
carried over from the engine and
eliminates oil drips from the end of
the breather hose. The chrome canister
is divided into two chambers,
allowing the oil to settle out before
the crankcase air is expelled through
the filter. Canister is chromed aluminum,
bracket is chromed steel.
Includes a long life K&N filter.

Krankvent Crankcase Pressure Control Valves
Evolution ® engines have unique venting problems because of small
crankcase volume and a relatively long stroke. The Krankvent solves venting
problems using high-tech materials combined with innovative design
that improves performance and significantly reduces the build-up of pressure
that can cause oil leaks and seepage at gasket joints particularly in the
top end. Easily installed on all models.
