I put 1.5mm shims in my 700 this morning and was very disappointed in the results. It seems to have the opposite affect of what it is supposed to do. There is more lag in throttle response, rear tires hardly spin off the line. Any ideas why? Or what I may have done wrong? Pretty much followed the A YouTube video.

More then likely you dropped a weight or two out of their channels...... You need to hold pressure against the cam plate when installing the movable primary sheave assembly......Then verify full cam plate engagement before installing the nut and washer

The belt MUST be all the way down the primary and all the way up the secondary sheave when the installation is finished...

Thanks Vincent. You were absolutely right. I had 2 weights out of position. Live and learn. Now that I have had that primary sheave apart it is quite evident why it has to be compressed during the whole process. This was the first time I have ever taken one of these apart. I watched a number of YouTube videos but don’t remember any of them mentioning that part, if they did I sure don’t remember it. Second tear down went much faster but having overfenders makes it more of a pain and time consuming. Took the 700 out for a short spin and am now happy with the results. Got my new 1” wheel spacers installed too. Looking forward to spring and taking it up North for real workout.
Thanks again.

You are not alone, I did the same when I did the shim mod. I too saw no mention of holding that plate in any video. I have great bottom end in life range, but hi range it was a slug. I contacted a guy that does cvt clutch work and machining locally, took my bike to him and as soon as the cover came off, he saw my belt position abs said I had flipped a weight.... Took it apart abs sure enough, one was laying sideways.... 300km I drove that way... Lol

Actually glad it happened, it made me pull the trigger on lighter weights & machined sheave.... What a beast now!

So I am wondering about this mod, I work my machine pretty hard, plowing, pulling deer, pulling logs, moving boats, an such. Is this mod any good for my machine? What does this mod all take to do?

This mode does work well. It's works even better with a stiffer spring

This YouTube link will show you how to do it. The results is better low end power and quick throttle response.
If you think 1.5mm helps (and it does) can you imagine having the equivalent to 3mm of shims?

Stock is 2:45 :1 initial cvt ratio, with 1.5mm of shims you get about 2.75:1 initial cvt ratio, with my Coop45 sheave +0.5 shim I'm at 3.1:1 ratio.

That's impressive. That must pull the front end up off the ground quite easily. Did you loose much top end? I don't care a whole lot about top end speed because I rarely go that fast, but it is fun getting there quick. Do you do any plowing with it? I may add a stiffer spring later, right now I don't want to get it to the point that it's to hard to finesse the throttle when plowing or hauling a trailer full of firewood. This is the only thing holding me back from doing more right now.

My bike does over 60 mph on gps... And remember I only have a 37 hp 550 with heavy Growlers tires . That's the beauty of a machined sheave. You get your cake and eat it too!!!! Way more of the line torque with basically no top speed loss.

I don't plow or do much work with this bike. But I do alot of slow technical riding and yes the extra low gearing is awesome !!! High range ends up between high and low, and Low is just ridiculous when compared to stock cvt . Low speed crawling was much improved on my quad. Again when compared to stock.

A stiffer spring will slow your CVT from shifting up. Keeping you in a lower gear longer. It also improves back shifting ( down shifting) . Your engine braking will be stronger. And it adds clamping force on the belt witch will prevent slipping in extreme duty situations

All good stuff. I just might have to do the secondary spring next summer, I won’t be doing much more than plowing or hauling firewood this winter. You recommend the purple spring with the 1.5mm shim? That seems to be the most popular.

Yes,

I'd stick with the Epi purple, as they seem to work well for 90% of 700 Grizzly / Kodiaks out there.

I measured mine finally, and after machining, and no shim now, I'm just a hair over 3:1,
so I'm intrested to see where i sit with the 0.5mm shim added back in

everything vincent said right here is spot on, my 700 kodiak hit 104kph(64mph) stock with slightly heavy 26" reptil radials. Now, after machined sheve, griz weights, and purple spring, I hit 108kph, (67mph), and at a much quicker and smoother rate.

oh yeah, in hi, i barely have to put effort to lift the fronts, in low, if i punch it hard, I can't keep it from lifting the fronts, mind you I'm a big guy 300+ and naturally sit further back on the seat. But I find throttle control is better now, finessing over objects is easier, so I think you will have no issue plowing.

purple is a very good choice, especially along with the 1.5mm shims.

Thanks guy's, I am now all the more interested in doing the purple spring, and will most likely order one in the near future.

Got my new 1” wheel spacers installed too. Looking forward to spring and taking it up North for real workout.
Thanks again.
How are you liking the new spacers?

The new spacers are great, only wish I would have got them sooner. I got a set of 4 one inch spacers on Amazon for only$63.

Great you like the extra stability. I enjoy the handling of 1" spacers all around on my quad as well!

All the mods mentioned here make the machine more fun and take off better.
Since you intend to use it also as a heavy hauler I'd recommend the wet clutch slug kit. It will fully engage the wet clutch at a slower speed so it doesn't slip when you are pulling heavy loads at slower speeds. Keeping the wet clutch engaged will keep the oil cleaner and make the engine last longer.
And use low gear too.


I picked mine up from JBS.

I've read great things about wet clutch slugs, and mite do it to my next bike. But them making your engine last longer, I call BS on that one....

When someone is **** on the wet clutch (slow heavy pulling, or significantly more power than stock) the abrasives from that wet clutch get released into the engine oil and can cause issues. By keeping the wet clutch living longer everything in there works like it supposed to.
