Ok, I'm interested. But I have a lot of questions.
1. How many grams are the OEM Grizzly roller weights? The stock 700 weights are approximately 18.5 grams each. Stock 660 weights are 17g and stock Kodiak 450 weights are 14g.
2. How many grams are the Fix torque kit roller weights? Sorry, but I want to know what I'm buying.: This is not something that they publish and per our agreement with Fix about releasing sensitive information about their kit for proprietary reasons, we will not be releasing this info. I do know that they weights that are provided are lighter than stock weights and you can buy even lighter weights for an additional fee.
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? Not really sure about this one. I will say that I havben't noticed a difference on our test quad so when we went to lighter weights initially so if it was higher or lower, it wasn't noticeable enough to note.
4. Are engine RPMs higher or lower than stock when cruising at low speed? I don't have an RPM gauge on my quad so I don't know the answer to this. A $90 highlifter gauge would make this study possible.
5. Are engine RPMs higher or lower than stock when full throttle is applied? I don't have an RPM gauge on my quad so I don't know the answer to this. A $90 highlifter gauge would make this study possible.
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? It isn't specific to a tire size or altitude range. A smaller tire size would make the sheave more aggressive feeling due to the gear ratio change that a larger tire puts in place. So, what that means is if you're running smaller, hence lighter tires, you're going to feel a more susbtantial difference than even I did with the heavy 26" XTRs.
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. I do not have a stock 700 to be able to test on but the gains should be close if you're testing the same bike before and after the sheave install. We have not been able to do a top-speed run as of the time of the revierw but will be able to do so soon.
3TV said: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.
