clutch and jetting questions 2000 polaris xc 700 sp

[Gerald Jerry Laurence]

Hi,

Ive been reading and searching google groups for awhile, trying to
find
recommendations for clutching and jetting of my 2000 polaris xc 700 sp
(1200 miles). My sled is bone stock, except for 192 studs and 8"
carbides. I aggressively trail ride only. Average speed 40 - 50 mph,
very rarely am I over 70 mph(top speed not a concern). Once or twice a
season I might open her up on the lake, but i am not a drag or lake
racer. I ride in michigan and in Huntsville, Ontario area.
0 - 2000 ft category.

Ive read XC pilots posts with interest (thank you) and think im gonna
go with:

1370 G needles
185 MAG - 180 PTO jets

Is this reccommended for a gas-oil-ride-do all my own standard
maintainence kind of guy?

Also Im looking for a clutching setup for this sled. Remember that I
am stock except for studs/carbides. I may add a SLP single pipe and a
boost bottle in the future (but then I can always re-clutch, if
needed)

One of my friends reccommended (but he had a highly modified '99):
EPI yellow primary
EPI purple secondary 2nd hole
EPI progressive 50/36 helix
go up 2 g on flyweights
and to drop 2 teeth on top sprocket

an older post for a 99 xc 700 had a recommendation of:
Polaris dark blue or dark blue/white primary
Polaris silver/white secondary 2nd hole
Polaris 50/36 helix
62g flyweights (assuming 10-62)

also is there a standard chart showing the colors of polaris springs
and their
respective lb/in ratings (or similiar) so I can compare them with
other manufacturers springs?

any input would be greatly appreciated, as
I think will be in the garage between christmas and new years, working
on the sleds, instead of riding this year (no snow)
maybe i can replace the skis with atv tires as one of my mods this
year ;)

Thanks again,

Jerry in Detroit

I rode a 2000 xc 700 last year and tried a few of the things you mention.
The EPI helix is shit, use polaris or similar helix. A 50/36 is the way
to go. A polaris silver/blue secondary spring works good or the epi
yellow. I ran 185/180 jetting all year with no problems and good gas
mileage. Use 1371G needles, they work great with good mileage and no lean
midrange. I also used a boost bottle, cleaned up the low speed response a
bit. Don't gear down, you'll go slower and over rev. As for primary
weights keep the 60 gram stock weights if using the 50/36 or use 62 grams
with the stock helix, the 2000's aren,t very strong and won't pull both
but will pull one or the other. 192 is too many studs, I'd use 120, maybe
144 at most. Good luck.

Thanks alot for the response.
Ordered the jetting stuff at the dealer, but probably wont be here for a
week.
What would you recommend for the primary spring.
It is currently stock (almond), or should I just leave it alone.

Looks like i am going riding, were finally getting some snow!

thanks again,

Hi Jerry
Sounds like you would be more concerned with fuel economy than drag racing. I
would suggest trying perhaps a blue-gold or dark blue clutch spring in the
primary. This will lower your engagement and low speed cruising rpms. Even just
lowering your engine speed 300 rpm at trail speeds will make a difference. Last
year on our Quebec tour we had two identical 800LE's. Mine had an almond spring
and Bill's had a blue-gold (shorter and a bit softer). At trail speeds (60 mph)
he would rev 6300, mine revved 6600. We traded sleds a few times so I know this
to be fact. At the pumps he would consistently use 10% less fuel than me. My
sled was set slightly leaner (on the main jets) as well. You may need to go down
in weight a bit (maybe from 62's to 60's) to keep your max rpms around 7900 at
full throttle. Don't try for over 8000 you will lose performance. My 2000 was
happiest at 7800-7900 even with twin pipes. Having now had a long low altitude
tour (in Quebec) I recommend 1371G's (center clip) even in the cold at low
elevations. My 2000 was on the tour last year and on the second day we took the
1370's out and put the 1371g's back in for the duration of the 1600 mile trip.
The driver said it was to rich with the 70's and liked how it ran better with
the 71's. We had two mornings that we woke up to -28C, it was cold!!! If you
want a complete clutch kit Randy @ RB Specialties has a good one for 700's. He
is at 320-763-8500.

Terry,
Can you give an overall review of the pros and cons of your clutching
against Bill's?
I am not sure why his would not be better all the way around.
But I don't know a lot about it. Enough to be dangerous I suppose. Maybe
your clutching is more responsive when you whack it?

Thanks.

Terry,

Thanks for the advice.
I will definately be getting those 1371g needles now.
I ordered 1370g' s but now ill just have more stuff to add to the "tuning
tool box"
I will call RB specialities too, I was gonna try to peice together the
components, (saving $$) but sounds like he is well recommended

My main goal was to clean up the blubbering and plug fouling and to try to
get a "crisper feel" but also definately get better gas mileage.

I was definately the "gas pig" out of all others that I rode with, even the
800 and 800 to 1000
big bore cats.

Ill find out tonight if im gonna be in muskoka/huntsville, ont or in
gaylord, mi

Let it snow!

Merry Christmas and thanks again,

Jerry in Detroit

You might get him (RB) to sell you a partial kit, I did not know what I was
getting so I did not try. If you have a set of 10/64's you could try to get him
to send you the springs and helix and use your own weights. Just a thought.
Merry Christmas

Hi Bully
There was more to my clutching than I explained in the post (Cat secondary)
because I did not want to get too long winded. Anyway, you are correct in
assuming that my clutching was more responsive than Bills'. For general riding I
liked the setup I had. By general I mean cruise a bit, have a couple drags, ride
the trails to the burger pit and go home. For all day distance riding (aka Rob
Lyons) my setup was a bad choice. We were going far and I was burning to much
gas. Bills also had a more comfortable, relaxed feel to it on the trail. His
setup was 66 gram lightning weights, blue-gold clutch spring and a silver blue
driven spring in a stock 01 800 roller driven. Mine was a bit quicker-when it
was working right, but thats another story-I don't have the LE anymore. Bills on
the other hand revved almost the same at full throttle, backshifted well, and
got better mileage. If I had it to do again I would set up like Bills and fine
tune from there. In fact that is what I am going to do with my XC800, which
comes out of the box feeling more like Bills sled than Bills did. I mean it revs
even lower and engages lower than Bills 01. It also gets outstanding mileage.
Can't give you a number yet I am only on the second tank-but it will be good.
