It already has the seals installed. It comes with grease and weights as well.

I'm running my weights as I had previously replaced my factory weights with 4 Kodaik 450 weights and 4 Grizzly 660 weights. Because I didn't have access to a scale to see how many grams their weights were, and b/c only way to give true before and after results, using my weights was the best way to get accurate results. Additionally, Fix does actually sell a lighter weight kit that can be used rather than the ones that come in the kit. However, the ones in the kit ARE lighter than factory Grizzly 700 weights.
I hope that helps.
Thanks!

Ok, I'm interested. But I have a lot of questions.
1. How many grams are the OEM Grizzly roller weights?
2. How many grams are the Fix torque kit roller weights? Sorry, but I want to know what I'm buying.
3. I suspect that engagement RPM is not changed with the new sheave and roller weights, because the springs on the wet clutch are not chaged. Is this correct?
4. Are engine RPMs higher or lower than stock when cruising at low speed?
5. Are engine RPMs higher or lower than stock when full throttle is applied?
6. Is this kit for 25" tires, or oversized tires? And how will this kit work at higher altitudes, such as 6000 to 9000 feet, which is where most of my riding is done?
7. How about some more objective data, such as timed runs from 0 to 30 mph, and from 0 to 60 mph with a stock Grizzly 700 vs a Grizzly 700 with the only other mod being the Fix sheave and roller weights. And how about a top speed number for a stock Grizzly 700 vs a Grizzly 700 with the only mod being the Fix sheave and roller weights.
Thanks,

BusterW,
If I may, I'd like to chim in & reply to a few questions 3TV had. If I'm outta line, just let me know ... of course, it'll be too late for this reply, but I'll know for future replies ... :dontknow: bowdown
3TV,
I also have a machined sheave from Fix Power Sports, however, I purchased one for a 660 Rhino. (NOTE: I own a 660 Grizz & I bought mine a while back before this one came out for the 700 Grizz)
To answer your questions from what I've learned ...
Your question 1 & 2 - How many grams are the rollers ?
A. My first question to you is, do you have over size tires ? If you do, you need a clutch kit.
And, if you already have a clutch kit in, use THOSE rollers !
I can hear your reply, "Well, why do I want to buy this kit & not use their rollers ??" ... The Fix PS kit I assume comes for stock tires. If the rollers they send are the same weight as the stock 700 ... well, it never hurts to put new parts in.
AND ..... you MIGHT be able to get a machined sheave someplace else with no extra "parts" .... but it'll cost you just as much. So if you can spend the SAME money & get some new parts, the required grease (which is a quality grease), why wouldn't you buy this kit ?
Question 3 - Engagement RPM ? ...
A. You can get a tach from any Yamaha dealer. (At least I've seen them on their web sites) ...
I have a question for you ... Do you know at what RPM your Grizz engages ?? I sure don't. But, I do know, that with this Fix PS sheave ... it engages "Right Now" ... There's no hestitation, no lag, no wait for RPMs to build. It "FEELS" that as soon as I "TOUCH" the throttle, the bike is moving. I had to try this several times to realize just how smooth & quick the engagement was. At what RPM ? ... Who cares ??
Question 4 - I went rid'in yesterday. Hit snow, slush, mud & a lot of dusty dirt road. I also got to run mine flat out a little. Here's my impressions.
It takes almost no throttle to cruise at 25 or 30 mph. I was totally amazed at just how sweet this sheave is. And, if you're cruising & stab the throttle (my motor & pipe are stock except for this sheave & the Dalton clutch kit) ... the ass end of the bike squats down, the front end lifts & my bike just "Jumps" out & I'm hitt'in 45 or 50 damn quick. My buddy who rides an 07 Polaris 700, asked me after a few of these "C-ya later dude" stunts, "What the hell did you do your bike ??"
Anyway, your question was, Are the RPM's higher or lower than stock when cruising ?? ....... I don't know .... & personally, without a tach, I could care less ..... I'm just hav'in to much damn fun punch'in the trottle & do'in power slides like a sport bike !
Question 5 - RPM's higher or lower at full throttle ...
A. Dude, you need to buy a tach so you'll know what your bike is turning, cause I have no idea. I know I hit 58 MPH yesterday damn quick, before I had to shut it down for a turn, but the mototr was still pull'in hard. I mean ... I had so many bugs in my teeth form grinn'in .... it reminded me of fly'in down a dirt road on my Banshee. The performance is just flat unreal for a Grizzly. Oh yeah, not sure what your Grizzly weighs in at, but I figure mine is close to 800 lbs. (639lbs wet, winch, all the addons I have, extra gas, 27" 589's on steel wheels, folding chair & table, tools, shovel, etc ... & not counting my 240 lb fat ass) .... one more thing ... 58 mph on a Grizzly is faster than I really need to be do'in on that bike on a dirt road.
Question 6 - Is the kit for 25" tires & you ride at 6 to 9K feet.
A. I would guess the kit is for stock tires. But again, if you have oversize tires & a clutch kit already, stay with those rollers (IMO). Hav'in said that, I believe in BusterW's writeup, he mentioned you can get heavier rollers from Fix if you ask. Tell Fix PS what size tires you have, & maybe they'll supply you with some new rollers for the larger tires.
I ride at elevations of 5000 to 10,000 ft. So far, well ... I can NOT state how impressed & pleased I am with this machined sheave from Fix Power Sports.
7. How about some objective data ....
A. Now I'm sure BusterW will try all the time runs for ya when he can, but are you so skeptical of his evaluation, that you need that kind of info ?? Are you drag racing your Grizz ?? Cause I find timed runs don't mean crap when you're in the mud, snow or rocks. What's important is "Grunt Power", power to pull the machine thru the mud, etc. And believe me (& BusterW), this Machined Sheave from Fix Power Sports deliver's the goods. It has been the absolute best $250 + dollars I have ever spent ! .. Period !
Now, I hope I didn't ruffle any feathers here, cause I sure didn't mean to .... but when I read all your queations, I got the impression you didn't believe BusterW's evaluation ... So I have one last question for ya 3TV .... Has BusterW ever lead you astray before ?? I'd like to bet not.
Reguardless, if you don't believe his "WOWSER" remark .... then be a Manly Man, buy the sheave (I mean, it's only money & you have to have a reason to go to work, right ?), run your own tests, do a write up & call his bluff .........
But remember, I bought the sheave before BusterW did his write up ..... and I feel he's holding back ..... that's my "Hav'in So Much Fun" opinion.
Last question ... How many different names did ya call me while read'in this ..... :laughing7: :laughing7: :laughing7:
Later .....

:headbang:
I didn't call any names Gunny, it actually made me laugh a little because I didn't see it coming. Who said I doubted Buster? I just wanted to know a little more about what I was going to order.
I don't really care what the actual engagement RPM number is, ... ie 1000 RPM stock vs 1012 RPM with new weights and sheave. The number doesn't matter, I just wanted to make sure it didn't raise the engagement RPM like some clutch kits do. I've done some clutch tuning on Polaris, Kawasaki, and Yamaha ATVs before, and on the Prairie 700 you can create headaches with a primary spring that has too high of a stall rating, because as soon as the engine RPM drops below engagement RPM, engine braking goes completely away (the belt disengages). So as soon as you let the engine idle down for a super technical downhill, you're in neutral! I know that the Yamaha CVT is different than Kawi's CVT, and that the Yamaha CVT belt doesn't disengage, and the Yamaha CVT doesn't have the same kind of primary spring. It has a wet clutch instead, and the wet clutch springs are not changed with the Fix kit, so the Fix kit should not change engagement RPM. I just wanted someone that has used this sheave to verify for me that as far as they can tell engagement RPM feels close to the same. High engagement RPMs don't do well in rock crawling, like they do in mud. And we don't have mud around here, just dry rocks, wet rocks, and snow covered rocks.
I'm curious about full throttle RPM because of the clutch tuning work I did on our Rhino. I have a Trinity sheave, that comes with 12 gram weights (stock Rhino weights are 16 grams, ... see, that wasn't so hard, was it). I'm not trying to get "proprietary information" so I can build the same thing for less money, because the cost of roller weights is nothing in the big picture anyway. I just want to know what mods I'm actually making to my Grizzly. I'm pretty certain the "Trinity sheave" in my Rhino is just a Grizzly sheave that Trinity adds 12 gram weights to, and sells as a kit (I'm fine with that, ... and it works great). There are no machining marks on it, and it looks just like an OEM Yamaha part. Despite the probability that it is just a Grizzly sheave, it really helps on a Rhino. It effectively gears down the Rhino at low speeds, and it can rock crawl over technical terrain super super easy now, whereas before it was geared too tall, and would bog and not even have enough power to get the tires turning from a dead stop if you were up against a rock ledge and trying to get going. The new sheave made far more difference with the Rhino than either intake mods, or exhaust mods, or both put together. And it is QUIET! You get better performance without the extra noise from aftermarket intakes and exhaust. It is the best mod I have made to our Rhino. And with my Rhino it increased top speed from 46 mph to 53 mph (I have a Dynatek CDI on the Rhino). But despite the faster top speed, the Rhino feels like it is actually running at a lower RPM at wide open throttle when it is at 53 mph than it was at 46 mph with the stock Rhino sheave. The decrease in roller weight size in the Trinity clutch package increases engine RPM at low speed, where you need more RPM for more torque and power to get the tires turning. But the different tapered sheave actually decreases engine RPM at wide open throttle. I just wanted to know if the Fix Grizzly sheave did the same thing for the Grizzly. I don't need a tachometer, I just wanted someone to tell me if it feels like it is wound out more at wide open throttle, or if it feels like it is wound out less than with a stock sheave for any given speed.
As for the objective date: -- timed speed runs. I'm just curious is all. With my clutch tuning work in the past I have no doubt that clutch mods are where the money is at with CVT equipped ATVs. I just wanted to know how much difference it makes with real numbers as well as "seat of the pants". You can't blame me for being curious can you?
One last question. You have a Fix Rhino sheave in your Grizzly, and Buster has a Fix Grizzly sheave in his Grizzly, ... are they the same part? If they are not the same part, does one part give more performance than the other? That would be something worth knowing. I plan on getting one, I just had lots of questions is all.

3TV,
Dang, good to hear you're not upset with me .... :icon_thumleft:
You mentioned the Trinity sheave helped your Rhino in rock crawling & I assume back shift or should I say, the "Engine Braking" going down hills ??
That is another area I noticed improvements in yesterday. After I put the Dalton CLutch kit in, which does change the Primary clutch spring & the roller weights, (not the wet clutch springs like the EPI kit however), I noticed I still had to use a lot of brake going down steep inclines.
With this Fix PS sheave, the engine braking works better than it did when I bought the bike. Now, I've never run stock 25" tires, I had 27" put on when I bought it. But, now with this sheave, I'm happy again.
As far the part numbers of the Rhino sheave I got & the 700 sheave BusterW got, I doubt very much they are the same part number. I may have to check the web site again & see.
I bought the Rhino sheave becasue I have a buddy with a Rhino & all he did was talk it up & I wanted some more "Grunt" with these tracks I had just bought. I figured, hell, it's 660, same motor, why not give it a try ... & I've never been so pleased. From what BusterW wrote, this sheave for the 700 is a new product Fix PS has just put out.
And, BusterW may slam me, but here's what I know about the roller weights I had, came with my Rhino kit, & the ones I'm using.
The stock 660 rollers I have weigh in at 12g. The ones that came with the Rhino sheave I have, 14g. The Dalton CLutch kit for 27-28" tires & 3 to 6K elavation, 16g.
So, I used the 16g rollers in my Grizz witht he Fix PS machined sheave. And I don't plan on try'in any other rollers. I'm way pleased at how my Grizz performs as is.
And I'm new to this "Snowmobile" type clutching .... Dang !

Hey guys, lemme chime in here a little bit.
3TV, I didn't think you were doubting me. I just assumed you were a cautious purchaser and wanted more in-depth detail than was provided in the review. I will actually go into the review and add some detail in regards to the questions you've posed once Fix responds to some of the items I was uncertain about.
As for RPM, as I said, I just don't know what RPMs it currently engages at but it didn't seem to change that. Frankly, I don't see how a sheave could change engagement RPMs since the springs aren't changed on the secondary. I opted for leaving my Kodiak and 660 weights in b/c I was assuming it was a lighter combo than the provided weights since they also offer an even lighter set of weights. I'm running 26" XTRs which are pretty darned heavy IMO.
As for the relation between the Grizzly and Rhino sheaves, there is indeed a difference. The Rhino sheave is designed to be more agressive so as to better thrust the additional weight of the Rhino. I am left to assume that should you put a Rhino 700 sheave in a Grizz700, you'll get a much more agressive low-end to mid-range power gain. On a purely stock machine, without the additional weight of larger tires, bigger bumpers, storage boxes, fuel canisters, etc, it may even too aggressive and not a pleasure to ride which youl wouldn't want. This is purely a guess and without having the chance to do such a test, we can't know for sure and assumptions are worthless.
We would actually now like to test a Rhino sheave in our Grizzly since it does have that added weight and see how it performs. If it performs well and is still manageable, this could be an additional sales option for Fix to push for people with a LOT of additional weight added to their rides, especially if the rider is heavier than your average rider (which seems to be more common than I would have expected).

Thanks Buster, there's lots of great information on this site. We have two Grizzly 700s; the wife's is stock except for 27" XTRs, and we use it for plowing snow and trail riding, and it will likely remain stock. Mine is used just for trail riding, and I have done some fairly aggressive riding with it, including one ride that was 275 miles long, in one day. I would like to continue to do more challenging rides with my Grizzly, perhaps even some endurance events like Barstow to Vegas, or even a border to border trail ride on the Great Western Trail. Right now it has 25" Terracross tires on it, and I plan on keeping the 25" tire size because of better high speed handling. I have already ordered a full set of Ohlins shocks for it, and when they get here I can certainly do a review on them if anyone is interested. I do have a Uni oiled foam air filter on my Grizzly, but no airbox mods. I also plan on ordering the Dynatek CDI, and Fasst Flexx bars with Rox risers. I don't want aftermarket exhaust because the noise is too fatiguing on those before daylight to dark:30 rides. I've had aftermerket exhaust on a number of sport quads, a few utility quads, and on our Rhino right now. If I didn't have to re-jet the Rhino each time the exhaust is changed I would go back to the stock exhaust in a heartbeat. The noise is just way too irritating. What I want for my Grizzly 700 is an aggressive, powerfull ATV that handles superbly, and can be ridden for hundreds of miles at a time without problems. The EPS equipped Grizzly 700 was the perfect platform to start with.
I'm thinking that the Rhino Fix PS sheave may very well be a better choice for me. Even if it is a tad too aggressive for technical rock crawling, I still have the wife's Grizzly that I can take on those rides. Any idea when you folks are going to be able to do direct test between the two Fix PS sheaves in a Grizzly 700? I suppose I could always buy the Grizzly Fix PS sheave, and then when you folks do the comparison between the two sheaves, I could change to the Rhino Fix PS sheave for my Grizzly if it turns out to be better, and put the Grizzly Fix PS sheave in my wife's Grizzly.

Much more of a diplomatic reply ... bowdown bowdown bowdown ..... You-Da-Man !!!! ....... :icon_thumleft: :icon_thumleft:
I'd be interseted in that 700 Rhino & Grizz sheave test. That would be very interesting. It would be interesting to see what weight rollers they sent with Rhino sheave. Reason I say that is, you mentioned in your review the weight of the 700 Grizzly rollers & they are heavier than mine from my 660. I wonder if that was becasue of the EFI or just something Yamaha changed becasue of customer comments ?? Interesting.
BusterW, you mentioned you run four rollers from 450 & four from, was it a 660 ?? I've heard of guys doing this, yet as I mentioned to 3TV, I'm new to this snowmobile type clutching. So, could you or 3TV explain why you would run different weight rollers ?? To me, it doesn't seem like the sheave would be moving out (or in) as crisp as if all eight were the same weight. And, it would seem to me, the heavier or ligther rollers would be worked harder than the others ??
Or, is it nothing like that, & say, I take four 14g rollers & four 16g rollers, install them in the sheave, I end up with an overall average roller weight of 15g ? ... Which would be like "Fine Tuning" the clutch ??
Also, could you tell me what weight the 450 rollers weigh in at ??
Thanks for not telling me to butt out earlier, :icon_thumleft: & I hope I didn't get on 3TV's nerves earlier. :boxing1: I'll try & maintain :bs: ..... no promises however .... JK ... :laughing7: :laughing4: ;;s;;

The purpose of going with Kodiak and 660 weights is simply to get the overall weight down do the clutch engages harder/faster. My post to Gunny where I answered each of hi questions told the weight diff in the weights of a Kodiak, 660 Grizz and a 700 Grizz. As long as you keep the weight on each of the 4 sides of the ramps evenly dispersed so the sheave is balanced, you can put whatever combo you want. Some folks have even gone with 4 Kodiak weights for an even lighter setup but I've heard it's prerty aggressive and ends up losing a good bit of top speed. The idea of losing top speed from lighter weights is that they aren't heavy enough to fully push out the sheave so you're losing some gear ratio.
Does that help?

3TV,
For what you want, it is POSSIBLE that the Rhino sheave on your Grizz may end up being a great alternative. I wish I knew for sure and could make a solid recommendation for you. I also wish I could say that this is something that we'll be given the oppportunity to give a full test and comparison on for Fix. If given that opp, I would definitely do some comparative testing between the two which would enable you to make your decision.
However, this would have to be something Fix saw an interest in from you guys before they would commit to it. So, if this is something that interests you, I recommend you speaking up as I know some of you are running a lot of heavy gear in addition to some very heavy tire/wheel setups and that may be a perfect option for certain people.
Thanks!

3TV, I'm not a fan of loud exhaust at all. I can't have it with neighbors so close and I plow snow as well. The Swamp Series exhaust from HMF makes some nice gains and is very quiet. If you add the quiet core supposedly it is quieter than stock. I couldn't believe how quiet it was, with only the spark arrestor. At idle it is like stock and when you're on it is just a deeper sound. If you do a search I have sound clips on this site.
I'm also adding PwerMadd's Rox Signature Series Risers and FasstFlex bars on. I have them sitting in my garage. I"m hoping to get them on tomorrow if I can ever dig myself out of my house work getting the outside cleaned up ready to go for the summer!

I would definitely be interested in knowing what the difference in aggressiveness would be between the Rhino Fix PS sheave and the Grizzly Fix PS sheave. I think someone would need to test both of them back to back to be able to say, just because of all the variables involved. Gunny has a Rhino sheave, but has 16 gram weights. You have the Grizzly sheave, but less than 16 gram weights. The problem is, both the weight size and the sheave taper effect the same thing, ... effective gearing and acceleration. I suspect the Grizzly sheave from Fix has a different taper to it than the Rhino sheave they sell, but that may not be the case. It may be a different part number simply because the package for the Grizzly sheave comes with heavier weights than the package for the Rhino sheave, or vice versa. I think I'm going to have to call Fix and talk to them when I place an order. I'll tell them I want the more aggressive package for my Grizzly. Worst case scenario would be that I buy one of each, and find out the sheaves are the same. In that case I just install one in each of our Grizzlys. H'mmm, ... now I'm wondering if the wife is going to want a more aggressive clutch in her Grizzly. Maybe not.
I'll have to see what they say. Thanks for the info, and the great review.

The difference in the Rhino and Grizz sheave is more than just weights as they had a lot of engineering and R&D costs invested in manufacturing a Grizzly specific sheave.
Should we get a chance to do a review on the Rhino sheave on the Grizz, it WOULD BE a back to back comparison with computer data between the two. To do so, we will get a box that will test time trials, G-forces, etc from any speed to any speed to give everyone the comparison you want between the two packages with a loaded machine setup. However, we must have visable interest from the consumer for this to be feasible.
3TV, obviously, you are one interested person. Other people interested in this should let us know so Fix can see it here or we can relay the interest to them.
Thanks!
