Fusion 900 clutch

[SnowScooter]

So Ive been searching here along with many other forums on setups people are using in their clutchs for the 900. I know anything will require fine tuning, I am more or less looking for a starting point as I dont have much experience with this. I see a lot of people running the "719" helix with success, but it is no longer available. I have found many others running a 66/44-.46 with heavier weights in the primary. Is that basically the same as the 719 helix? The numbers look close, but as I stated...pretty green in this area.

My fusion is basically stock besides some durability add ons. I have the 115 belt, primary clutch was shimmed and rebuilt by indydan, torque link, and some vents. Other than that I have Vforce 3 reeds and a timbersled intake. It has a 1.5"x121" ripsaw track w/ stock gearing, and most of my riding is trails since I live in MI. Would the 66/44 helix work out for me with a little more weight to bring my R's down? It currently hits about 7800rpm with stock.

yeh most are using that helix you stated...its the best for flatlanders for sure...or at least something in that general area..

you can search on ebay, ive seen alot of them on there...search under team helix, tss-98 helix and go through them and look at the numbers..

you will be fine running any of theses..

66/44/46
66/46/46
64/42/46

and so on...just make sure you do NOT run anything less then a 42 as the middle number (so from 42 up 46 in the middle) and a 44 as a finsih number (so 44 or 46 as last number) and do not drop below 64 as a first number and you will be just fine..

they are running these helix cause they hook up fast with lots of traction, reduce belt heat and do not stress the crank as much as the chitty stock helix did..

if you have a stock pipe, you should run your MAX Rpms around 7400-7600 rpm...this is a huge debate, but i personally belive 7600rpm is best for that motor with a stock pipe, and 7800 is best with an SLP pipe..

hope that helps..

 

[guidoxpress]

also,

you should give the Team Black/White spring a try in your secondary...it helps bite the belt and is recommended by indydan as well.

if your over revving or not pulling enough rpm, adjust your weights, or primary spring

Sean, thanks again man...I (Luke) thought about emailing you since you have helped me out so much already on my fusion, but didnt want to bug you. I called babbits today (local dealer) and she said that helix is available. First track 66/44-.46 second track is 66/42-.46. Sound like a good idea? So far based on your advise and what Ive read, that is where I'm leaning. I will order the spring you suggested tomorrow also to go with it. Should I put a derlin washer under it? Ive read a couple post with people doing this...what is the benefit, less friction?

And for the weights, I think 74g is stock. My max rpm shown on my sled was 7800, so I figured the 76g should bump me back down around 7600 correct? Or should I look into the spring also? I was under the impression the spring controlled more engagement than top rpm. I also dont have a pipe, it is stock w/ a can for less weight.

hey luke...lol. good to know thats you, i cant keep track of people anymore, lol.

yeh i would snag that helix as long as its not too crazy priced...

i use 2 derlin washers...one aon EACH end of the spring cups, this helps the clutch rotate and not bind the spring up when it up/down shifts and goes into reverse..MUCH less friction.

you can try lighter weights, but for 200rpms, i would try the primary spring first...with a lower finish rate...not sure what spring you have now...but for example...if you have a SLP blue/pink spring rate of 140/340...you can drop to a polaris black/green spring of 140lb-330 lb and this will lower your final shift out rpm but keep your idle/clutch engagement where its at if you like when it engages now..

post your springs now, and what altitude your at, and we will help you out buddy.

 

[SnowScooter]

Ok, I will get 2 washers then with that spring and helix for my secondary...Parts dep. gives me a pretty decent discount at babbits since I spend half my salary with them.

both of the clutchs on my sled are bone stock...previous owner never touched them. I sent the primary out to indydan to have it balanced/rebuilt. My altitude is basically sea level...but never above 1500ft. Ya I know, weak...I wish I could ride some deep powder in the mnts. Stock says its black 120/310 in the primary

Hey SnowScooter, I am a flatlander also with an '06 fuse 9. You are definitely in the right direction with the helix. I have been running stock springs primary 120-310, secondary 140-240 (secondary on '05 is different think was 155-222?) so if you have an '05 go with the 140-240. Weights 11-76 and helix 719. RPM's for mine is about 7600-7800 which is a little high. Just received a 66-44-.46/70-44-.46 helix recently but have yet to try it to get rpms down. Also the finish on the 719 is same as stock 42 finish angle so wanted to try a higher finish. Have 11-74 weights also incase rpms come down too much. Love the 11 series compared to stock 10-74 they hit harder on the bottom and mid. Tried them before putting the 719 on so I can see what difference they made. I'd recommend you the 11 series maybe in 74 and 76 also. They say they act like 2 gram heavier then 10's so for 10-74 go with 11-72 but to tell you the truth I tried from 10-74 to 11-74 and didn't notice any change in rpm up top, just bottom and mid response as why I also went to 11-76.


EDIT- Also on the 9 is a Dynoport pipe/y-pipe/can combo, timbersled airbox, slp torque/push arms, cobra track.

I havent heard anything about the 11 series weights...when I found them, I assumed they were for a different style clutch. Thats some interesting results though, I will have to try those out. I planned on buying a few sets of weights and a couple different springs to fine tune. I dont have a pipe though, so not sure what difference that would make. Not sure how close the helix I am ordering is to the 719, but it looks to be the same angles?
What color is your secondary spring? I am curious also, did the 06 fuse come with the tss-98 or the tss-04 secondary?...and would that make any difference in setup?

The helix is a good choice. It is very close to the 719 helix. If you are going to get some extra weights to fine tune with definitely go with the 11 series. I have the SPRING-CLUTCH(90.9#)P2 7043149 secondary spring that replaces the original red/black 140-240. Not sure why they changed the spring to the one for P2 clutch I guess same weights. As for the secondary the fuse comes with the tss-98. The tss-04 is same just lightweight and same angles you would use for helix but they have different parts, not interchangeable.

Not sure what year yours is so would go with either red/black 140-240 or red/pink 140-260 secondary springs. Primary Almond 140-330,almond/red 165-310 for higher engagement if you'd like, Blue 120-300, black/green 120-340 are good options for the primary depends on what you use for weights. And either 11-74 or 11-76 weights.

Right now I am using stock primary spring 120-310, have a 165-210 for higher engagement. Just put a new SPRING-CLUTCH(90.9#)P2 7043149 which replaces stock secondary 140-240. And 11-76 weights turning as I said 7600-7800 will try the 66-44 helix when I get some time think it will be better then the 719.

 

[SnowScooter]

Sounds like I am on the right track then. I will start with the stock primary spring 120-310 and get a black green also 120-340 since I like the engagement where it is for the trails around here. And I will get 11-74, 11-76 weights to try.

The secondary I will get the red black spring 140-240 and the team helix 66/44-.46. Also a couple derlin washers for the spring.

 

[guidoxpress]

i do not recommend using the red/black secondary spring...its too light and doesnt grip the belt very hard, and slows shifting.

i would ONLY use the Black/White or Red/Pink spring in the secondary.

good luck bud.

 

[SnowScooter]

Ok, and what about primary? I am thinking of trying stock first with the 11 series weights. Should I reconsider that also?

 

[guidoxpress]

just make sure your primary is shimmed for the 11 series weights...i think they are different then the 10 series ones...ask indydan or Biggdawg, he will know if you need to or not

 

[sno_mo_racer]

I wish I did order the red/pink now also. Will have to get one soon then. As for going from 10 to 11 series you will definitely have to reshim your primary but will be well worth it.

 

[SnowScooter]

Ok, I did read a post on polarisfiles that said you need to re-shim the primary for those weights. So I will probably try the 10-76 first, but I bought both sets to try out. The stock spring will work though since I want to keep my engagement where its at? Or should I be looking at something else with the heavier weights?

So if you are using the red/pink (140-260) secondary spring, should you be using the blue/pink (140-340) primary? Basically the first number should match.

Guido, I was looking at your '05 buildup page and noticed you are using the red/pink or black/white for secondary and then using the blue/pink or green/pink primary.

Also, noticed that you have added weights to the outer hole on your mtx weights. Is it easy to add the weights if they are all ready installed. I prefer not to take off the primary to add the rivet weights? Thanks for your time and input.

the first number of the springs do NOT have to match, the first number is the primary spring is basically what rpm the clutch will engage in, i have found the black/pink is great, and so is the blue/pink....the green/pink was a little high for me...


use the red/pink or black/white secondary springs...i use all blk/wht in mine

the MTX rivots are easy to adjust...just remove the weight, slide the rivot in and smash it on a piece of steel or whatever...just dont hit the weight...you drill them out if you need to adjust them...very easy...and great weights!!

Using black/pink, what are you engaging at? I think I'm engaging around 3800 using the blue/pink? Little jumpy but don't mind.

Definitely going to make a valentines order tomorrow for myself and order the red/pink and black/white. Can you tell the difference between the red/pink and black/white, does the red/pink shift faster? Is the 2 gram weight the one with the hollow hole?

Thanks for the help! You and many others on the 900 forum have helped me out tremendously the past couple of years getting my fuse dialed in.

 

[SnowScooter]

Are the MTX weights better than the 11 series weights for low to midrange? Also what is the stock primary spring colors?

On a side note I had my belt deflection set wrong, so I adjusted it and man did that help that sled out....made it a whole new machine.
