By Sarge McCoy
Two riding buddies and I purchased
2016 Polaris RZR XP 1000s. Mine is
the only one with a driveline vibration.
We drove them from the dealership to
the gas station a quarter-mile away.
Then I immediately drove it back to
the dealer. Polaris installed a new
replacement front driveshaft, but I still
have that metallic sound and vibration.
They say they can do no more for me.
Sarge, what do you suggest?

Boot, you most likely won’t get
anything further from the dealer,
because they don’t know what to
do next! You need to have driveline
professionals help you if you want to
remove all the noise and vibration. You
have two types of vibration at work
here, Boot—transverse and torsional.
Transverse vibrations occur once per
revolution and are usually caused by
an imbalance in the driveshaft. Have
the driveshaft balanced by a shop that
specializes in driveshafts. Torsional
vibrations occur twice every time the
driveshaft rotates. In RZR XP 1000s,
it is not an excessive U-joint angle but
an out-of-phase driveshaft. Phasing
is aligning the yokes at both ends.
Again, a driveline shop will have no
trouble doing this. Finally, the factory
carrier bearing sets the driveline at the
wrong angle for smooth, vibration-free
operation. Replace it with a Sandcraft
Motorsports carrier bearing
bearing-carrierassembly). Do all these
things, Boot, and your Zooter will be
the smoothest and quietest of your
group of riding buddies. Twenty-five sit-ups, Boot! Dismissed!
CAN’T SEEM TO
GET MY HISUN
I recently purchased a Hisun
HS 700. Ever since I got it,
it has pulled to the right. The
dealer said it was tire pressure.
I have increased the right front
tire pressure over 5 psi above
the left front tire to counteract
the pull to the right. Can you
tell me how to straighten out
my Hisun, Sarge?
Boot, did you even check out your
dealer as to their reputation before
purchasing? Chances are, if you did
some advance recon, you would have
discovered what you now know—
their service department is staffed
with high school dropouts! You don’t
adjust pull by over-inflating tires! You
are now on report for following their
stupid instructions! Return the tires to
the recommended inflation pressure
now, Boot Loosen all the tie-rod
adjustments. Align the front wheels to
back with string, adjusting the tie-rods
as necessary to get the front wheels
pointed straight ahead. Now, adjust
the tie-rods until the steering wheel is
straight. Finally, adjust the tie-rods so
each front tire toes inward 1/8 inch.
This gives you the correct 1/4-inch
toe-in that I recommend. Measure the
toe-in with a long straightedge from
the back of the front tires at the center
of the tires. Then do it again from the
front of the front tires at the center of
the tires. Your Zooter should now track
straight and most likely handle far better
than it did when you picked it up from
the high school dropouts! And, don’t
think you are getting out of this with
just being on report, Boot! On your face
and count off 50! Dismissed!
SLUGGISH AROUND THE
I was left a 2005 Honda Rancher
400 by my grandfather. He drove it very
little, and it just sat in the barn when
he got sick. I restored it, and it runs
fair, but it feels like it is stuck in high
gear all the time. It is the automatic
transmission model. I don’t know
anything about it and hope you can tell
me what to do to fix it.

P.S. There are no “error codes.”
Boot, you may have thought you got
a good deal from your grandfather, but
that model had some ECM problems. The
transmission wouldn’t backshift to low,
leaving you operating in high range, hence
the “sluggish” performance. Back in the
day, Honda Canada covered the upgrade
for free. However, that “free” upgrade
expired on June 1, 2007. My guess is,
Boot, you will have to pay for that “free”
upgrade to restore your grandfather’s
Zooter to optimal performance. Although,
you can always ask! Dismissed!
HOW DO YOU GET THEY-A
I recently purchased a used 2005
Kawasaki Brute Force 650. It has a skip,
and the previous owner told me he never
changed the rear spark plug. I can’t see
the rear spark plug, so I don’t know what
to remove to get at it. I have no owner’s
or service manual.
Boot, it is not uncommon for lazy
owners to put off difficult or unpleasant
maintenance tasks. The rear spark plug
on your Zooter is a bit challenging to
change. There are basically three ways
to change the rear spark plug, Boot. You
will have to choose the method. First is
the factory way by removing the air boot
off the top of the drive-belt cover. Second
is remove the battery. Third is use a long
extension with a universal joint. You will
need NGK CR7E spark plugs and an
air compressor to blow debris from the
spark-plug hole. With three choices you
might wonder which one Sarge uses.
I choose number three, because I am
confident I will not break a spark plug or
cross-thread it when reinstalling. If you
are not confident in your mechanical
abilities, Boot, then go with number one.
Also, since you don’t have a service
manual, get one from here: http://www.
A week on KP, Boot, for not purchasing
a service manual before doing any Zooter
