do I clean the KVP?
it from the hoseclamps, snap it open then wash it in hot, sudsy
water, rinse and let it air dry. Then reinstall. DO NOT use
compressed air to dry it. Also stay away from harsh solvent
Is it possible to install the unit backwards?
but be careful not to. The KVP is marked on one end with a grooved
ring. That is the EXIT end of the unit that will lead to an
do I mount the KVP?
KVP is not restricted to position. It can mount vertical or
horizontal. Pick a place to mount it then run the line to the
unit. Watch for sharp bends or crimps in the line. You do not
want to restrict air flow.
if my bike breathes through the heads, do I need 2 units?
Simply install an after-market head breather adapter kit. This
will connect each line to a 'T' or crossover bar. Drop a single
line from the bottom of the T that will connect to the KVP.
Place a short hose on the 'EXIT' end of the KVP and run that
to your filter.
if my bike breathes both top and bottom? Can I still use the
suggest you plug one end and breathe through the other. You
can plug the top end by replacing the hallow bango bolts with
solid bolts. Then install the KPV on the remaining line coming
directly out of the crankcase.
it matter if there's a filter on the end?
the KVP puts you in a negitive air flow (3-5 pound vacuum) it
does suck in a small amount of air and that air needs to be
clean. We suggest a filter 3-6 inches after the KVP.
is the 'milk shake' looking liquid that collects in the KVP?
is merely condensation with a bit of oil in it. It will not
hurt the unit. Most bikes don't see this. If the KVP is closer
to the heads, it may collect some condensation. Simply snap
open the KVP and wash it with hot sudsy water, rinse and reinstall.
I get replacement parts?
you can always get pieces to any of our products directly from
us. The only thing you may possibly need on a KVP would be an
umbrella valve and that would be only if it became contaminated
with gasoline as gasoline will cause the rubber to swell and
the KVP restricted to a specific bike?
We can install on any bike that has crankcase pressure. (ex:
Sportsters, Big Twins, Baggers, Customs, Fuel Injected, etc.)
Just be sure to address ALL the breathing areas. We want to
be sure we're capturing all the air pressure.
