I have one on my bike. I put it on because I always had a small amount of
oil coming out of the breather hose after riding. I did not notice any
change in performance or sound as they state, but I did not dyno test it
either. It did solve the oil problem though. There is not a drop from the
breather hose or krank vent, so I am happy with it.

motor breathing through both the heads and the crankcase.
The motor definitely sucks in through the breather. Didja ever notice that
the MoFoMoCo puts the exact same umbrella valve in the rocker boxes that
Hayden uses in the Krank Vent? I can't imagine that HD would engineer those
umbrella valves in unless they decided they were needed.
I've dynoed my bike many times with and without the Krank Vent and it made
no difference in power anywhere on the curve.

know.. they do nothing but plug up an drip oil ...your motor breather only
has a positive pulse out never in thats all bull... any motor builder will tell
you that you dont need a filter on the end ......as far as your 18 miles a
gallon if you think back you may of freshen up your motor or rejetted your
carb or bumped up compression all will increase gas milage.....or even changed
pipes

You are completely wrong on this one bud. Think about the
design of the late model valve covers. Why do you suppose
there is an umbrella valve in there? And why do you think
the Hayden Krank Vent uses a check valve? The whole design
point of the Krank Vent is to maintain a net vacuum in the
crankcase. This would only be possible if both pressure
and vacuum pulses existed at the breather. Indeed they do.
Check it with a gauge if you don't believe me. How many
other types of engines (cars, boats, etc.) have you seen
with unfiltered crank case ventilation? Coincidence? If
you don't filter the end of the HD breather hose hanging
by the ground, you *will* suck dirt in the motor. Don't
make gross generalizations about "any engine builder" until
you have had the opportunity to talk to them all. Perhaps
you are basing your claims on drag bikes which don't run
breather filters, but then they don't run air filters either.
A completely different agenda there. For a street machine,
it is just plain dumb not to run a breather filter (or an
air filter). But hey, what other folks do to their motors
ain't money out of my pocket.

az's reply reminded me to let you know that the spyke krankvent, IMHO is a far
better product, and costs about the same.
the hayden uses a check disc like the hd umbrella valves. if they are the same
material, umbrella valves don't last(or so i've heard, i don't have 'em on my
'88).
the spyke uses a nuclear grade material in theirs which has an unlimited life.
the spyke looks a lot better, chromed with or without mounting tab.
the hayden looks like an inline gas filter.

not around here at least.
my independent shop recommends a filter, or at least 12" of hose to prevent
intake of road debris. seems he's had to work on several breather chambers that
did get screwed up.

any motor builder maybe, except me. I have dismantled motors with unfiltered vents
and found ROCKS in the breather chamber. The acoustics and airflow of the breather
hose are very much like the exhaust pipes, pressure waves and reversion and all of
it. Filters are a wonderful thing. Use them. Patrick

no way a breather hose will suck anything in not dust or dirt or rocks.....you
do have to turn the fitting around on the oil pump so your line is faceing
down......if there are rocks they fell out of your head into the motor....just
kidding had to say it.........patrick your exhaust pipe will suck nothing into
it an eather will your breather vent

I gots one of these fancy schmantsy PCV valves on my scooter only
because it was free.
To tell ya' the truth, on an 93 and up EVO if your umbrella valves are
working right, there is no need or benefit.
Spend your money more wisely, like on some of those nifty braided
stainless steel plug wires ;-)

face it king, you went out on a limb, it snapped, you hit the ground<g>.
seriously, like i said before, i've heard the same thing from respected
wrenches who actually do the rebuild work on hd engines.
you may want to recheck your sources.

Which motors do you work on that have the
breather vent coming out of the oil pump?

filter? jan 1st 1978 (i.e. 1978 1/2 models) were the first HD's that were
vented to the intake, feds said no more open engine breathers, i remember
that because i was a wrench for a dealer in YORK PA when this change
occured. A vent filter or a PCV style valve may be helpful, but I have
never seen anything drawn up into the breather valve from the breather,
seen plenty of ruined breathers from trash being sucked from primary ( pre
wet clutch). , breather valve should be closed when pistons are on the
upstroke, creating vacumn that then moves oil from crankcases when the
valve opens and pistons are on the down stroke, if breather timing is
correct, there should be no drawing atmosphere into the breather, if this
is not correct, then please educate me to how this system works, being open
minded is a good way to learn,
