Post by KDOGG49 » Tue, 19 Dec 2000 14:23:37


I have a new used ZL this year, I bought a D&D clutch kit, single pipe, and
power breather for it.  Can anybody help me out with what main jetting changes
I need to make, so I don't toast it?  Currently I am running 340's with it
stock.

0 to -20 deg. F.  They have burned one with 410's.  Make sure you put in the
Q-3 needle jets and run your clip on two.

I run 430 MJ & Q3 in second clip - sled seems very strong in midrange
and very fat on top end.

My wifes has 430 mj & Q-3's (clip in two) and it too has awsome midrange,
but sometimes I can't get it to pull over 7000rpm, especially when cruising
for a while.  I whack it, and it lays right at 7K.  I haven't had a chance
to check the plugs at WFO, but they look real close to perfect in the mid. I
rebuilt the clutch when I put the weights in it.  D&D says it could be the
stator, but I always thought they just "went".  D&D also said it could be
the clutch kit I put in (not theirs, mine), though I don't know how if I'm
pulling the full shift (8100) from a dead stop with the stock helix.

what's your clutch combo?.  Maybe i can help you out.  I have a book
full of cat 500 setups that people have used.  Have you tried using the
q3 in the third slot?

Nope, haven't tried the 3rd slot.  I tried the ***lever though and it
stayed right at 7K w/ the throttle WFO. I put in "cat" 60 gram weights with
an arctic orange spring.  I just picked up som Poo 62's (10AL) that I will
try with a stiffer spring.  The secondary is stock but I have a 58/50 that I
may try with the stock spring.  What'da think?  Thanks Mark!

Hi Jim
It may be just a typo but 10AL weights are 52 grams, not 62. Just
thought I would point this out for Mark who is trying to help.

Hey Terry, BTW, I checked the piston wash on this and it was perfect.
Wouldn't want to go leaner, at least not in the mid. D&D guaranteed the 420
mj was too small. I'm hoping these Polaris weights do it.

help with 98 ZL 500 jetting

Post by xcpi.. » Sun, 24 Dec 2000 03:20:09

Are you still chasing that flat (7000 rpm) top end problem? You better
fix that before the wife gives you a spanking. Seriously, you have not
been trying to run 60 gram weights in that 500 have you? That sounds
way heavy. This is a ZL 500 with a D+D pipe isn't it. Interesting on
the jets, usually D+D plays it VERY safe on the jet specs. Remember on
the piston wash that it will take quite a while to wash off the pattern
from your old setup-which you may have been using for years. Also, if
your sled is only running 7000 at full throttle, you probably are not
running it there alot. My point is, maybe you haven't run enough full
throttle to get a proper wash reading.

help with 98 ZL 500 jetting

Post by sleepe » Tue, 26 Dec 2000 06:49:40

I am ashamed to say, I already got a spankin'.  Wasn't bad though.;-)  So,
I'm probably jumping the gun on the wash.  I'm trying to throw 10AL's in it
which I believe are 52 grams.  It will pull it from a dead start right to
full shift, but can't pull it from a rolling 30 mph full flipper.  It just
lays there (maybe it's the way she broke it in ;-). My questions to you wise
one, is, can a Poo weight over a Cat weight make that much difference?  Can
simply a stock helix not be the "right" angle as to not let this pipe come
on?  Is it possible that a 58-50 could solve the whole problem?

help with 98 ZL 500 jetting

Post by xcpi.. » Thu, 28 Dec 2000 12:11:51

I am wracking the archives of my brain, trying to remember some of this
stuff. The 10AL's you have were used on the RXL 650's back in 1990, and
the 57/50 Cat helix was one of our favorites back in 95-96 before we
all went to rollers. The 10AL I think would be a fairly hard pull for a
500,our 650's didn't pull them with much authority (like 8000 rpm). The
10 series weights from Polaris pull fairly hard, what rpm are you
trying to pull with the pipe? The purpose of the 57/50 helix was to get
rid of an overrev condition the 800/900/1000 Cats had on full throttle
between 0 and 60 mph. It might help your sled, but I think either your
weights are maybe a couple grams to light or your driven is not
backshifting due to perhaps being not wound enough or to weak a spring.
Did this problem start when the pipe was installed or was it there
before? Are you using the yellow spring in the Cat driven or something
else, and do you have the stock roller on it? What helix is in it 51,
53, 49? How many miles are on the sled, could anything be worn out? We
are heading to the lake tomorrow for a few days, I will check back
later tonite to try and help before we leave.

help with 98 ZL 500 jetting

Post by sleepe » Fri, 29 Dec 2000 01:46:37

Looks like I missed ya Terry, thanks though.  I am trying to pull 8000 rpm
with the pipe.  I have the stock roller with the stock helix (?), and the
yellow spring.  It only has 2000mi. on it (my wife doesn't ride like Rob L).
The sled ran good previous to the pipe except for an annoying flat spot
around 5800 rpm, where she did most of her cruising.  I think that was
carburetion though because it would get terrible mileage when we rode civil.
The 10al's are 53 grams.  I have 50's in it now.  It pulls 8300 from a dead
stop.  Just won't pull it from 30mph.  Thanks Terry
