RZR 1000 CVT COOLING
I have a 2014 Polaris RZR XP 1000
which I like a lot. However, when
I’m driving it hard on warm days, it
seems like the CVT clutch and belt
get too hot. I’m wondering if the vent-
ing to the clutch housing is as good
as it can be. A buddy of mine says
Polaris changed the design of the
2015 model to improve airflow to the
CVT. Do you know if this is true? If so,
would the parts fit on my 2014 model,
or is there something else I can do to
get more cooling air in there?

It is true, and Polaris has a retrofit
kit for the 2014s to bring them up
to 2015 standards. It’s part number
2205862. The kit includes: 1) Drive belt
(3211180), 2) clutch cover, 3) Frog Skin
covers intake, 4) intake tubes and 5)
Mounting hardware. Retail pricing
is about $260. Note that Polaris only
recommends the use of belt #3211180
with this upgrade kit. Field reports
say you can expect a 40-degree
Fahrenheit reduction in belt temps.
PROJECT QUAD ADVICE
I started riding years ago on a
Honda TRX250R and then switched
over to the newer 450s. I miss the
older two-strokes, though, and I’m
thinking about building a project
quad using a TRX or a YFZ frame.
What I’d like to do is install a big
two-stroke engine from a CR500 or
KX500. These have kick-starters,
which I don’t mind, except for one
thing: I’d like to use the nerf bars that
have the built-in heel guards. They
don’t allow room for the kick-starter
lever to swing back. So, I was wondering if any company makes an
electric-starter conversion kit for the
CR or KX engines. If anyone would
know, I figured it’d be you. Thanks for
Dave, my boy, both motors have
been converted to electric start;
however, not by any company that
sells kits. All were created by backyard mechanics—very skilled backyard mechanics (i.e., machinists).
According to rumor, you can take a
Goki ATC350X starter kit and make it
fit the CR500. Goki can be contacted
here: www.goki-storm.com or (818)
998-0852. The KX500 was converted
by a guy in Australia using KTM 300
parts. See here: www.dirtbikeworld
Without a machinist living next door,
it is going to be quite a bit of work
to get these motors to spin over with
electricity! Have you considered a
KTM 450 or 530. They have a factory
electric start and two extra strokes!
HOW OFTEN SHOULD I TAKE AN
I purchased a Yamaha 350 Moto
4 from a yard sale, and they said it
ran, but I cannot get it to start. The
local dealer’s mechanic told me
that the engine stator cover seals
are shot and needs to be replaced. I
asked him how did he figure this out,
and he said that there should be no
oil in the stator compartment. They
want to charge me $1000 to get the
whole thing apart. Boss, I only paid
$75 for it!
Your dealer’s mechanic is an
idiot! When that quad was built,
your mechanic was most likely
still in grade school! Those stators
always operated in a splash oil bath.
Remove your spark plug and pour
a bit of gas down the hole and then
see if it fires up. If it does, then it’s
a simple carb cleaning to get your
yard-sale find running.
I have a 2007 Kawasaki Brute
Force 650 4x4. It has been a good
machine that has never let me down.
My quad does have many hard
miles on it now, and I figure it’s time
to give the engine a rebuild. Instead
of going to the dealer to buy new
pistons and parts, I was wondering
if there’s a performance company
By Winston “Boss” McKannick
that sells everything I need as a kit?
Maybe even different levels of kits,
with hotter cams and a stroker crank.
Who do you know that would have
the best prices on that? Thanks for
your expert advice.
If your Brute was a 750, there
are a number of kits available, but
it seems like the little 650 was forgotten! You may have to do it the
old-fashioned way—order parts
from multiple vendors, like EPI
clutch springs, maroon primary and
almond secondary, Dynatek CDI,
full exhaust (like a Big Gun, HMF),
Hot Cams camshafts, Wiseco pistons,
and Hot Rods connecting rods. Kev’s
Performance lists a 1000cc big-bore
stroker kit for the 650 with crank,
rods, pistons, sleeves, and cams.
Contact them at
bore-stroker-kit/ or 919.207.0010.
Some of my buddies have old
Honda ATC250Rs, and they have a
pretty good time riding them at the
dunes. I have a garage full of old dirt
bikes that I don’t ride much, so I was
thinking about converting one to a
three-wheeler. I figure I could swap
out the swingarm from an ATC to
have a bearing carrier for the longer
rear axle. However, I don’t know
where to get wider triple clamps for
the front forks to clear the bigger tire.
My buddies tell me you know everything, so I was hoping you’d have
some advice on which companies I
should check with. Thanks.
I think your buddies are confusing
me with that arrogant jarhead from
the other magazine (UTV Action)!
