Application: CRF250R
Honda's all new CRF250R is nothing
short of an awesome motorcycle; it
does everything well. The only area
in which it fell short to its
competitors in our bike comparison
was the engine department; Yamaha's
YZ250F is still the top dog when it
comes to making power. The CRF makes
good power but lacks the roll-on and
hard-hitting mid the YZ-F possesses.
That said, we thought it would be
the perfect candidate on which to
try the new
POWERNOW
PLUS™.
The
POWERNOW
PLUS™
increases air velocity by cutting
down on destructive, turbulent air
entering and exiting the carburetor.
At half-throttle, the air entering
the carburetor is very inefficient,
because it partially hits the slide
and begins to tumble inside the
throat of the carburetor. The
POWERNOW'S
septum, also known as the power
blade, splits the air and
increases forward momentum. The rear
POWERNOW™
has been around for a while, but the
plus is a dual setup that uses a
POWERNOW in front and behind the
carb.
Installation is pretty straight forward. Once you remove the sub-frame,
simple slide the
POWERNOW™
into the back of the carburetor. To
assure proper alignment inside the
carburetor, the kit comes with a
locator pin that, when inserted
corectly, will line up with the two
small holes in the back of the carb.
Once the
POWERNOW™ is aligned on the front and the back of the carb, remove the locator pin
and re-attach the sub-frame.
Roughly 20 minutes later, our CRF was buttoned up and ready for the
track. For the test, we put the
little red thumper back in stock
form. Immediately, our test staff
noticed a difference in power. The
normally lasy roll-on received major
gains, and the added boost was
apparent all the way into the middle
of the powerband. The CRF pulled
harder out of corners and required
less clutch to build rpms.
For it's price, the
POWERNOW
PLUS™
is among the best performance hop-up
values on the market.
