    Modifications to 2006 Fusion 600
    Posted by Sean Ohio on Tuesday, September 30, 2008 9:57 PM

    New forum member and new to snowmobile ownership,  I have always rented sleds in MI and Canada on trips,  just this summer I came across (2) 2006 Polaris Fusion 600s at a local dealership and I bought them!  After researching I have come to the conclusion that before it hits the snow it will need some adjusting and modifications   ANY SUGGESTIONS?

    Hello sean. I have the same sled and my best suggestionj to you is start working out  your arms very much. They turn like a dead toad.. They have sooooo much ski pressure feel they are much differant than anyother sled i have had. They say the holz racing spindles work for 300 bucks. Never rode one wit them on.. Engine wise they area sturdy with any other 600.  Inquire from willie on the clutch stuff he tests all the time.  Willie can be found on this site just ask for him..Hope this gets you started

    SL44, I havent got my hands on working with the newer model on the fusion yet but if you really having that much of a problem with ski pressure, is there a limited scrap in front part of the suspension? If theres one, then loosen it up a little which it will put more pressure in the suspension and release the pressure on the skis. OR/AND you can play with the block setting on the rear of the suspension. Also look at your front suspension shocks and see what spring setting is setup on that. Check all of it out before you go and buy a racing spindles for them - anyone?

    WL,

    In laymens terms you are sugesting that the rear susp be softened inorder for there to be less front susp pressure?  There is an adjustment dial for the rear susp that can be changed from soft, medium, and firm.

    FIRST: Write down your VIN #'s and call your local Polaris dealership and make sure that all of the recalls and Bulletins have been completed on your two sleds (i.e. carb boots, chaincase bracket, fuel tank, etc.)

    SECOND: I don't want to speak for willie, but he has told me to go with the following:

    Carbs: 400 mains, 55 pilots, 0.9 air pilots

    Clutch: EPI Maroon Spring, 10-64 Polaris Weights

    THIRD: Everyone has emphatically stated that the Slydog skis work really well on the Fusions.  It is supposed to reduce turning effort and improve cornering.  I just bought a set to try this winter.  Also, the Bergstrom guys state that they can achieve the same thing with their ski-savers and shims on the stock skis.  I have some of those coming too to try this winter.

    I love mine and they are really nice sleds, congratulations on your purchase.

    WL,

    Correct me if I am wrong - usually if you have the setting soft, medium and firm by moving the RRSS, then the way I understand, the firm setting will not allow u to weight transfer as much as the soft setting would. If that the case, then the sled will not shift backwards which would allow it to lesser the ski pressure. Thats number one.   Number two, I know I have monkering with the EDGE suspension in the past with my step-bro's '03 XC6 and I forgot what the setup was like - its been 3 years since he sold it. Right now, I am on "googled" and search for Polaris Fusion rear suspension picture and Im going based by that... and it does look like theres a limited scrap in it.  Loosen it up and if its not enough, tighten up the spring preload on the front shock in the rear suspension - that will help to reduce the ski pressure for easier steering. Thirdly, another option is to loosen up the spring tension in the front suspension as well. You just have to find the right combo for your type of riding style. Try it and keep track of what changes being made on paper in case it doesnt work out - at least youll know where to change it back to. Anyone?

    Wl,

    Thanks for taking the time to help a new snowmobile owner, your message and suggestions on the adjustments for easing the steering are going to be helpful, I think until the sled hits the trails I will not know which setting is best.  

    Embarassed to ask the following, however I have disclosed these are my first snowmobiles, and I am going to have to learn sooner or later but the previous  thread mentioned the following adjustments for my new sleds 

    Clutch, EPI maroon + 10-64      secondary stock     gutted air box    400 main jet, 55-60 pilot jet, .0.9 air jet.

     Sorry, Is there a website or someone reading that can dummy this up for me, I truley want to understand the technicallities of my sled however I I dont know what any of the above means,  whould my dealership know and be able to make these modifications or is this something I can learn to do on my own?

    Doing the work isn't hard, but if you have never done it before you may want to find someone who has and help you walk through it.  Changing the jets in the carbuerators is simple, but its a little bit of a pain getting the carbs out and back in.  There are some exploded views on the polaris parts website you can reference http://parts.polarisind.com/Browse/Browse.asp

    The clutchwork is also pretty simple, but you need a special tool to get the clutch off.  Usually, a shop can help you out with this.  If I had more time I'd give you more detailed info, but I can't right now.  Try to find a local snowmobile club or shop and get some assistance.  Once you've done it once, you'll see it's not a big deal...

    QUESTION,  WITH THAT MAROON SPRING(185/320 RATE) AND THE 10-64'S YOUR ENGAGEMENT IS PROBABLY  RIGHT AROUND 5000 RPMS?? A LITTLE HIGH FOR TRAIL RIDING,

    I HAVE A SPRING 140/320 WITH THOSE WEIGHTS AND IT ENGAGES AT 43-4400 RPM

    The maroon spring and weights were recommended from Willie.  I have not installed these yet, maybe he can tell us the engagement rpm.  What spring do you have with the 140/320 (polaris, epi, etc)?

     Anyone know what the rates are for the stock spring (black/green)?

    EPI maroon should engage a 4600-4700 wich is high.  I've tried the yellow EPI or almond-red Polaris, same finish but lower engagment and I can't get the same performance compare to the maroon.  The maroon is so snappy from 0-30 mph, it's unbelievable!  The bad side of that spring is that you heard the ''clunk'' from the secondary when you stop to cross a road and go on the throttle after that.  But as I said before, this is the best set-up I have now. maroon is 185-310, stock spring black-green is 120-340.

    I know it make no sens, 2 grams more weight and a spring ending 30 pounds lower...  The engine should rev at 7500 with this set-up, but it rev a 7900-8100 wich is exactly the Target RPM to get the best HP and Torq for the 600HO CFI or not.

    It doesn't seem to make sense, but I'm gonna try it.  Looks like EPI has some good prices for the weights and the spring...is there any issue with buying their "economy" clutch puller?  The one I have is for the wedge so I need to get a new one.

    TO CHANGE THE SPRING AND OR WEIGHTS DO YA REALLY NEED TO PULL THE CLUTCH?? I DON'T THINK SO.  USE SOME MUSCLE TO GET THE OLD SPRING OUT AND THE NEW ONE IN

    Good  point...I'll try that first.  I ordered the spring and weights over the weekend.

    Good luck to install the EPI maroon without removing the clutch...  If you do, you are stronger than me.

    I highly doubt I'm stronger than you...I actually have a puller on the way.  I've never replaced springs and weights on the sled before, I've always pulled the clutch.  Alpine's method seemed reasonable, but in hindsight, you're right - this is an impressive spring so I guess I'll replace it the old fashioned way!Yes

    I got a little company reward this week, so I'm spending it by sending my pipe into Bikeman!  So I'll have willie's air-box, carb, clutch, and pipe recommendations ready for winter.  I hope it meets my expectations (understanding that it is still just a 600).  I CAN'T WAIT !!!

    OK Willie.  Spring and weights are installed, carb mods are done, Pipe was shipped to Bikeman for modification.  One more question:  I noticed my belt was damaged (split through an inner tooth through to the outer band...not quite all the way through).  It was an 080 Polaris Belt.  I have a spare 080 that I put on it for now.  SHould I continue buying these, or is there a better one with the same dimensions?

    No Problem,  as a new snowmobile owner I have tried to learn a couple of things from the chatter on the thread.   I am actually taking possession of both of the new sleds tomorrow afternoon.   I was considering not changing much on the stock sled, due to me not being that knowledgable about some of the modifications you all are talking about, also I am more of a fast trail rider, more than a ditch banger or drag racer,   I may just hang off on any modifications till next yr,  HOWEVER   I am still concerned about the difficulty in steering the sled (more for my wife and friends that will be riding with me and borrowing my second sled)

    Sounds good.  As for the steering, don't worry about it too much until you get a chance to ride it some.  Many people don't have any complaints...It really isn't all that bad and you get used to it after a while.  I only noticed it on long rides through tight twisty trails.  I'll let you know how I like the Slydogs and if they really do offer an improvement or not...Post some pics of your sleds once you pick them up!

    I only ride in Michigan.  We have an excellent trail network, two tracks, etc. and no need to trailer too far for great conditions.
