ok, this is my first sled... last season i shared a sled with my dad, a 2002 z570, because mine wasnt running, it had a frozen shock, and just wouldnt start... well last week i finally got my sled from storage, and towed it home on a flatbed because it wouldnt start and was too heavy to lift on my trailer, so i took the flat bed from work and towed it home, got home, and for the hell of it, pulled the cord 3 times and it fired up...
now as i said, this is my first sled, my dad bought it 2 x-mas' ago, and we never used it, until now.
but the thing is, i rode the 570, and i know i didnt do much riding, but i know i wanted to go faster. i have a modded out Banshee, so im not real new to the whole speed thing, only when it has tracks and goes on ice and snow
and i want my sled to be fast, now i dont want the speed of a 800 tripple or something, but if my 440 is gonna be slower than the 570 i rode last year, i know im gonna wanna go faster...
so basically i want to know what i can do to this sled after i ride it for a little while to make it go faster? porting? head mods? i couldnt find any reeds or pipes...

and also, i dont know what is wrong with it, but the sled takes off at 5k rpm instead or the normal 3? so my friend thought it was the belt, but i checked that, and it seemed fine, so im wondering if it is a clutch or something else.

sorry for the very long post, im happy to finally have a sled to go this season, cant wait.

thanks in advance, any help is appreciated...
Chris

i think the only thing you can get for it is a clutch kit. I have the exact same sled and it goes pretty good for a 440. I can beat my friends 550 supersport with it so i think your zl will be just about as fast as your 570. 5k sounds about right for engagement, your used the the low engagement of your 570. The reason for this is the 570 is fan cooled and makes more power at a lower rpm.

hope this helps :banana:

what about porting? is this a good way of getting power on a sled? i know it is for banshees, and also like shaving the head for better compression...

black magic might be able to...but im not sure. try asking in the general forum :dunno: i know that engine is pretty much the same as the engine in the old (around 1990 or so) prowlers...

i just talked to my friend, and he said he has ridden arctic cat, polaris, and ski-doo, and they all engaged around 2500-3000 rpm, so i dont know, it just seems kinda weird... i know im a newb, and i dont know sh!t about sleds, but it seems not right to jump from a sled that engages at 2500 and then jump on another and you have to duble that rpm, and it gets really loud, like its not supposed to be disengaged that high... right now i dont know, i havent gotten the chance to really look at it lately, they guy before me was a 26 year old sort of heavy guy, it was his first sled too, and he had it for awhile, and im sure he beat it. but it has only 1400 miles on it, which i thought was low for a 97...

1400 miles is real low. I am almost positive it should engage around 5000, thats where my 500 engages and the 440 engages just a tad lower than 5000. any sled that is fan cooled or has power valves will engage lower to make use of their low end torque...

oh ok, because its not like AT 5k, its at around 4700-4900. it just didnt seem right to be that high cuz it seems like its over-revving to take off at that point... thanks for clearing that up...
by the way, what is the name of that clutch kit, and do you know the price?
thanks,
Chris

also, i think i have a place around here that can port it for me, and mill the head if i want, and also rifle bore the carbs, the place is called Racers Edge Performance.
im just wondering if its even worth the time and money to take the top end off, i was gonna ask for a strong woods/trails port and the biggest available mill and still be able to run pump fuel...

Sure do, black magic makes a clutch kit its around $180. check on ebay, they are usually a hell of a lot cheaper on there. Also you can piece together your own kit by buying weights and springs, but i would have no idea where to even start in order to do this.

It probably has a clutch kits in that raises the engagement to get better hole shots. I think the liquid 440 and iar 570 had similar hp numbers but the 440 revs faster.

ok to clear up some things here....first the zl and zr 440 had the same motor. this motor has a very high stock engagement. stock should be around 5000 -5200 rpm. this depends on the belt, clutch wear ect... the 500 was the same. this motor has every possiblily you can imagine for aftermarket addons. to start i would get pipes and clutch it. dont worry about porting it yet. this thing screeeeeams with alot of other stuff. black magic makes the best 440 aftermarket stuff around. there is a 97 440 zr in my town that cannot be caught. that owner even prefers his 440 to his 2002 zr 800. my advice is not to port but to add stuff to enhance. this thing is a screamer just waiting to have the gag taken off. the only difference you will see with zl to zr is jumping.

thanks in advance,
Chris

Not trying to be an ass or anything, but i know for a fact you are wrong. :doh:

The zr440 (at least 97 and newer) engine has pretty much the same crankcase as the newer 500s and 600s and is case reed. The zl engine is pretty much the same as the prowler engine and is a piston port motor. The zr had about 90 hp and the zl has about 68.

OK, lets clean some stuff up. First, the ZL and ZR 440's aren't the same. The ZR's are a power-valve motor whereas the ZL's aren't. The ZR's are heavier all around. Your ZL will make about 68hp, within 3hp of you 570fan, but it should be faster. As for mods, a clutch kit is the only thing that I have found for ZL440's. You can get twin race pipes and can and whatnot for the ZR's, but that is because they are a powervalve motor and make more power to begin with. You should have a great sled, I had a 2000 ZL440 for a while. Lots of fun and plenty of power.

ok, so i will be faster than the 570? i ride in all kinds of terrain, but its usually in big open corn and tobacco fields, so top speed is kind of important, but also not because i like the twisties and whoops and stuff too, so now im wondering what top speed is, i got the 570 up to 80 acorss a field, probably could have gone a little faster but the whoops were getting too big, so i had to slow down, but will i be able to top this on the 440?
and another thing, a guy that looked at the sled last year said the shock was "frozen." i dont know what this means, so im just wodering, if i take the shocks that are on it, would i be able to take it somewhere to get them rebuilt?

the zl dosent have rebuildable shocks. It has ryde fx which are sealed. What dose he mean by a shock being froze? I doubt a shock is froze. If the suspension is moving up and down then nothing is froze. If something is binding or something, I would think something in the suspension its self is froze or not assembled correcly.

I have a couple of similar sleds (93 prowler 440s). I was able to find a mild trail pipe from AAEN, might not be listed for a ZL, but maybe give them a call and ask about the prowler pipe as we have the exact same engine. It really woke up the throttle response and top end of the sled, it is a stinger type single pipe, but its not too load, just right. No more heavy can under the hood either. I am not sure if our sleds weigh the same or are even geared similar, but all I can see out of the top speed is mid 80's to maybe 90 in perfect conditions. The pipe made a nice difference, as I put one on 1 prowler but not the other, and mine is faster now, and gets there quicker, and sounds way better too.

Other than "zrnewf"s clutching advice, there really isn't anything out there for our motor. The only thing I found was this pipe. Check out their website. Good Luck...Prowler

Specs from AAEN's site:
Prowler, Couger 440 L/C 91-96 Single PIA 10049 6 hp 12 lbs $ 399
Lose 12lbs and gain 6hp.
