Default Things to do to my 440 fan! Clutching? Pipe? etc..

Ok i know absolutely nothing about clutching so i need some help.. I dont even have a clue as to what i need to do.. So can anyone shed some light? Do i need new weights, spring?

Remember its the 440 fan.. Im sure clutching it will improve it a little right?

I am going to look around for a pipe for it, I figure i can keep this sled for awhile since im gona convert it to short track once i get a suspension, If i can find one for like under 200 or so ill prolly buy one for it if i have the chance..

Also can i put bigger carbs on it? If so i know i need to also get bigger carb boots, How big can i go and will i even notice a difference if i put bigger ones on it? I doubt this would work but could i put the carbs off the mxz on it? haha. They are like huge compared to mine so im sure they are too big if they could even get on there.

Also how about cutting the head? What exactly does that do and how does it affect performance? Will my engine be less reliable if i do that to it?

So ya any info would be great, Also how much would parts cost to clutch my sled?

Clutching will give you the best increase and a pipe if you can find one. www.dynoport.com
bigger carbs will not help and cutting the heads will only give minimal (.25 hp) increase.
If you can find a pipe, then rejetting will be necessary. If it only hase one carb on it, changing to two of the same size will improve throttle response and give a little more to the top end.

Ya the two main things i was thinking of doing was a pipe and clutching.

I didnt think the bigger carbs would do much but i thought i would ask and make sure, So ill stick to the carbs i got.

Ya cutting the heads would not even be worth it so thats out too..

I am going to keep searching ebay for a pipe to fit my sled. Ive been looking around and people say that DG pipes for my sled pop up every once in a while, and they said they were pretty cheap. So ill keep searching there.

Also which pipes could i use on my sled to increase power? Like could i use a pipe from a 500 and still get more power than stock? There is a set of homemade twins on SF. I dont know tho. I kinda want to get a single pipe as its better for everyday use right?

By the way its a dual carb already so im good there..


Im not sure which ill do first, clutch or pipe, just whatever comes along first. But i do need help with clutching it. I have no a single clue what to do haha.. Also how much is clutching it gona run me? Im hoping its not too much.. Maybe madcow can chime in and help out with clutching..


I think it will be a pretty sweet little 440 fanner once im done doing these things to it..

Dual pipes from a 500 will work, you will have to jet fat though.

There is a pic of the pipes on there, They are on a liquid, Should they still work fine and give me more power? They are homemade and hes asking 100 plus shipping.. Im not positive they are still for sale but he never said they were gona which was a month or two ago..


There was a guy on craigslist selling some twin psi pipes for a 500 i think but i didnt have the money, I wonder if he sold them already, I have no way of finding him tho damn it..

Shit i just posted on craigslist that im looking for a pipe from a 440 or 500 either a single or twin pipes, Right away i got a response.. This guy said he has a single and a set of twins. 200 for the twins and 100 for the single, So my question is, What do i want to shoot for? Twin or single, Which gives me more power? but i also want to keep the engine reliable, I dont know if twins or single make a difference or not but i think they do, but somoene will have to help me out.

The twins will give a greater gain with twin carbs also.
The single if you are sticking with one carb.

Might be stock Poo, whatever they are, make sure to get the manifold adapters as well, if you buy them.

What would they be stock off of? Ill make sure and get the adapters.. Do you think theyre worth the 200 hes asking? Just by the looks.. Im not sure i want to spend 200 on a pipe. I hope he will drop the price a little..

I just had a guy email me and tell me that anyone trying to sell a set of twin pipes is full of it cuz they dont make twin pipes for 500. They do make twins for 500 right? They are just hard to find..

As I saids, looks like stock pipes on a Poo, not sure of the model though.

slp use to make a twin pipe setup for the 500 indy.

for cluthing on the fanner we put on the aaen single and then dropped in a pretty good helix and secondary spring. worked real good. with the aaen single pipe we didnt even rejet, dropped the pipe in and put in the clutching. the sled sounded awsome and runs great, for a fanner it will suprise you.

I dont know how the motor will run with 500 pipes on there? if them others have experience doing it then go with what they say. but your fanner spins at around 7000 rpm and the 500 fugi spins at 7800-8000 rpm.

I thought so, That guy said he knows someone that put some 700 twin pipes on a 500 and changed timing and some other crap he said and it worked pretty good, He was trying to sell me a set of 700 pipes for 200 after telling me they dont make 500 twin pipes haha

Hmm that got me excited about piping it and clutching it til that last part haha.. Ill read up some more about the 500 pipe on the 440 and see. But i think it should work ok. I guess ill search around a little more..

Maybe i should wait before i decide to buy a 500 pipe. Ive read more than once that DG single pipes that will work on a 440 pop up once in awhile. I mean i ahve all summer. and someone said they are usually under 125. I could definitly go for that.

But then again, OCR said i would get more power with the twins. So im not sure haha..

Ya ill keep searching around for a pipe that might work better. Here is one on ebay for a 488 fanner, Im guessing that would work better for me, but its brand new and 300 plus shipping, Im not looking to spend quite that much, Maybe 200 at the most im hoping ill get one for less tho.. http://cgi.ebay.com/ebaymotors/ws/eB...2BSI%26otn%3D4


Does anyone know where else i should look for a pipe like this? i searched the forums like SF and HCS, Didnt see anything..




I dont know, I am considering converting it to liquid cooled, I know some of you say its gona be some work and time consuming, But i am up for it, I have the coolers from the mxz to use. If i can find a liquid engine ill prolly do that so thats another reason to wait to buy a pipe. If i find an engine for a great deal and have the cash ill pick it up.


Or i have a great idea haha.. Alot of people are going to haydays right, Someone could an engine up for me there, and ill give them the cash. I know SnowAttitude is really close to me in mankato.. Thats only about 40 minutes away..

Do you guys think i could get an engine cheap at haydays? I really dont care even if its a twin or a triple.. But if its a twin i want like a 600 atleast. Hmm.. What do you guys Think a 600 twin would run for up at haydays?

Ive got complete drivetrains for both a 98 440 ves and a 2k non ves 700 twin. Expect to pay about 4-600.00 for a decent hp 440 drivetrain and 700 large on up for anything bigger than a 500 liquid.

If I were you I would keep my eye out for a late model 550 fan drivetrain. They are quicker than you think they would be. Rode my cousins 03 touring 550 longtrack gen 11 whateveryoucallit and was moderatly impressed. Held its own behind Riley and myself in 2 miles of slush on the river. Thought for sure that big turd was going down. 0-70 it felt as quick as my 700 and the job would be a near bolt in deal where as a liquid retrofit would take you the better part of the summer before you saw daylight.

Well ill see what i can find, Just whatever i can find for a great deal or the 440 fan will be staying in, If i can sell the 440 fan ill have a bit of the money to put towards the liquid engine, I also dont care how long it takes, Ill enjoy doing the project over the summer getting it ready for next season, Ive got the tunnel heat exchangers taht i think should work pretty good for this project. Altho im not totally sure what i will all need to do this, Im guessing a coolant bottle and some hoses, Maybe i am not thinking about everything, If so please let me know..

Is there anything else i need to do other than put in the exhchangers, a coolant bottle, and some hoses?

^ Its not that long of a list but its definetly "A" list. Tunnel Coolers, a bulkhead cooler, hoses, coolant hose modifications, a seat that fits the conglomeration if anything is above the tunnel, coolant bottle and any misc. bracketry beit bought or fabricated from whatever.

For the drivetrain you will also have to adjust clutching, gearing, exhaust routing, airbox location, etc. Steering related equipment can interfere with engine plates, engine plates can require re-mounting... could be some of this or could very well be all of it. However,if some guy can bolt on a supercharged airplane engine to an old Kawasaki snowpro (that was probably fan cooled from day one), you can certainly do what you are considering. Via Condios

Ya thanks for pointing out those things, like the steering and all that, that may have to be moved depending on what engien i want to do. I didnt even think about that stuff. Ive got some tunnel coolers from an mxz i plan on using if i do this project, The rear hoses dont go above the tunnel so i wont have to do any seat modification.. I am also needing a new seat soon anyways..


But the bulk head cooler, The mxz didnt even have one of those, i am assuming i can get away just using the tunnel coolers. They arent those really skinny ones like some polaris have, they are wider so they should hold more coolant..

Well im not sure ill ever get around to doing this, If i come across an engine i can pick up for the project, I can almost guarantee i will start doing this project, So if i do i will post up a thread with the project..

Can someone with a polaris sled get me some good pics under their hood? I want to see where the coolant bottle is mounted and all that. I dont really know of anyones that i can go look at and i dont have any experience with them yet..

Ok i think i may have found what im going to do with the sled.. My 440 fanner might turn into a 600 triple! haha.. Theres an older 600 triple for sale, The suspension got messed up or something so hes selling it. Now it is an older one, i think 87.. So thats the only thing im worried about, Should i pick it up as long as its got good compression on all holes? Ill get the whole sled minus the rear skid i think, or maybe that goes with but i dont care i dont need it and its messed up anyways he said. for 200 bucks i can take the whole thing, Im going to see if he will take less on it, Here is this story tho haha.. I dont think this guy or kid knows much.. Its had a little problem apparently..

He claims his friend adjusted the carbs and made the thing run rich and they tried to start it and it backfired and the fuel lines caught on fire.. So the choke cable is burnt up and the fuel lines but everything else is fine it looks like.. I got one pic of under the hood, he said the sled is already tore apart.. So what are you thoughts? should i check compression on the engine and if its good pick it up? Ill have all the parts i should need to convert it right there..

One more quesion, Dont the water lines go through the chain case or the brake or some shit? Like i said i havnet hand any experience with liquids yet. Do i need to have mine set up like that or can i bypass that part and keep my same chain case?

And as you can see in the pic the choke cable is burnt up along with some of the fuel line i think.. Does it look that bad? Im thinking of picking it up and using it for my sled..
