I wanted to give a review on the coop45 mod 3 on my 2016 grizzly 700. Arnie was very easy to work with after emailing him to get the info that I needed to proceed. I ended up ordering a new sheave from him so I could keep the stock one. My set up ended up being modified sheave and orange epi secondary spring and stock weights. He told me I would get all the low end back and no top end loss. His set up did exactly that. I am very impressed with his work and the service and info I got from him . I asked all the questions from low end power to top end speed. The answer was use the parts the he selected for the low end and if you want more top speed add horsepower. It was about as simple and straight forward as it gets. So if you want to do clutch mods go coop45 custom clutch mods. Good luck getting service and info from the other guys like Arnie will give you. Satisfied customer here Thanks Arnie

@Luke4022, that's great info. About how much money are we talking here? Maybe I'll save my pennies and do that, then I would have a new Epi purple spring and a couple shims for sale, ha, ha!

I believe his fees are currently 150 US $ + plus shipping. Total cost for me was a bit over 300$ Canadian.

I do like the idea of gaining low end "grunt" without losing top end speed. I'll have to give that some more thought. It doesn't take very many cancelled "pizza nights" to pay $150.00 for something useful.

I also have Arnie's machined sheave and epi purple spring, he machined a new sheave that he got and the purple spring and sent it all to me as a package, plus I still have my stock sheave, very happy with Arnie's work and great customer service, thanks Arnie

I feel even worse about my (Other Brand) sheave now.. I spend $450 Canadian then another $100 Canadian for a set of 16 gram weights because the 18s didn't do what I wanted.

Its all sitting on a shelf because I got belt slip. I put stock back in and am scared to try it again...

I Really really wish I had called Arnie first.

Oh cool, so I could still use my purple spring. Hmmm, that makes it even more attractive.

@Madkawi750, yeah, that sucks man. I frigging hate it when that happens. Not enough play money to throw it away.

Just to make sure everyone is clear that the money mentioned above would need to be confirmed with coop45 but most importantly, that would not include a new sheave.

Hows does the Coop45 mod 3 with slightly heavier/bigger tires affect fuel economy on the new 708 engine? Anyone? When I finally upgrade tires I may have to upgrade the clutch.....but I really don't want to lose a lot of fuel economy.

If I am not mistaken, from what I had read on one of luke4022 post, I think Arnie sat luke4022 up with a orange spring just to let it shift out a little sooner then the purple spring. (Luke likes to ride fast) I also will be joining the Coop 45 club, mine should be here Friday or Saturday.

You will lose some, how much, depends on your riding habits. That is why God made rotopax!

I realized this is like comparing apples to oranges but in the case of my 550 grizzly I really can't tell much different in fuel economy between stock cvt and modified. What ever I lost in mpg is minimal. Also keep in mind my bike already had heavier 26" Mudlite XTRs when I purchased it.

I second this!
Since I live in Greenland, it would be too troublesome to send my sheave to him and all that, so I asked if he could order one for me, machine it, and send it back with a purple spring. He did, of course.
He gave me all the answers for my questions in a fast and polite manner. Thank you so very much, @Coop45
He sent me the package to Florida, where I have an address at myus.com (freight-forwarding company). I received the package today via Fedex, and will do the swap during the weekend, if my job 'allows me so'.
I am really looking forward to feel the change of my 2016 700 SE.

Again; thanks Arnie!
