Hey guys, new here but not new to cvts. I have a 2016 Kodiak 700 with a purple epi spring,18g weights and 1mm shim. I am going to do the coop45 mod 3 this week.My problem is I did the spring and weights at the same time and the results are great just rpm is alittle high.will the mod 3 get my rpm down alittle or do i need to go heaver with my weights? I should have done the clutch mods one at a time to get a better feel of what changed what...oh and my max speed is 55 mph (rev limiter)with 26" itp mud lights.im thinking 20g weights but I don't want to lose anything that I have gained..thanks

I did a similar thing when I installed my JBS sheave and spring. I installed the whole kit at once and was disappointed. I have 26" Reptiles and went with 18g weights and found that they were too light. Switched to 20g and now I'm happier. In the end, I should have simply stayed with a shims and added the secondary spring for $50. I don't need top end speed for the riding I do.

I would go with heavier weights. I kept my stock weights with my CM#3 +.5mm shim and purple spring, and it was more than adequate when I had my 27" Blackwater Evos. Now my 30" Inlaws are a different story....
I like the low end with no top end loss the milled shave gives. Like stated above, no I don't need to do 70 with my type of riding either, but we do a lot of back road riding to get to where we're going, and I don't want to be doin 10k RPMS at 45mph either lol.

Thanks guys, I'm thinking 20g grease less will put me right where I want to be. I need the high mph to go from trail to trail down the road.The Kodiak came with 30g so when I did the clutch weights and spring it was a big improvement. I like to be able to lift the front end in the trail so the more low end the better

And also does 55mph seem right with only a 1mm shim...and no I didn't do a ratio count
Honestly, when I had 1.5mm of shim with stock weights on 27's, I want to say I would max out around 60-62 before hitting the rev limiter. I could be wrong, that was a while ago. I would think with how light you are with your weights, that 55 might be accurate before hitting your rev limiter. It's all subjective however due to the different tire sizes. I cant even hit 56 with my 30's on. I have no idea how fast that equates to in stock tire size.

Yea I would think it would go alittle faster because I just put stock grizzly weights in it and 1mm of shim ..i guess a ratio count is in order just to make sure everything is working properly...

I recently did something simular.
I had previously added the 1.5 mm shim to my little 550 (noticable difference) and after a few months of riding, chose to upgraded my stock spring to an EPI orange. The performance gains with the spring were fantastic but the cruising rpms had raised by 500 rpms. The engine reving all the time was annoying. I switched my weights from the stock 16 grams to 18 grams and now I couldn't be happier.

Wow all this info and I'm on the fence on which way to go. I have 2017 grizzly 700es with ehs controller and airbox with lid and exhaust tip. Next is clutch work. I do a lot of mixed riding. Stock 26" tires. If I do tire upgrade I'm sticking with 26" radials nothing too heavy. I stay out of the mud if I have to ( pushing 60). I really would like to help the lag at take off for the most part. Drives me nuts sometimes. I was told clutch work will help the lag. What do you guys think?

Start with the shim mod. You will lose some top speed. I lost near 6 mph with 1.5mm shim. So if top speed is a big deal to you start with 1 mm.

Later on if you feel like experimenting, try a stiffer spring.

Do a search on coop45 mod #3. From what I have been reading it gives you a lower ratio than shims can,plus no top end loss.

Well it 80 degrees and sunny here in upstate ny, it's killing me not having the Kodiak together considering this is my first day off in 3 weeks! Can't want to get my sheave back...but anyway I was thinking about running my epi 18g weights with out grease even tho they are not grease less...do I just put it back together with out any grease? Or do I still need to grease all the other parts??

I would put the grease in with your weights if they're not greaseless. I'm not sure if there's a correlation or not since I'm no master of CVTs but my sheave got hot and all the grease flung out of it and after that happened, I had a weight get stuck and my grizz ran like a gutless pile until I pulled it apart and serviced the sheave and put the weight back into its correct spot.

I received my sheave back yesterday from getting coop45 mod #3 and installed it.First off I think I my have screwed up my rollers a bit when I switched clutch weights. Low end feels better, top end is great (67gps,36L) but it seems alittle flat mid range. When i switched my rollers they seemed kinda oblong, would this cause some mid range loss? Or I may be imagining things. By the way this thing rips and I have *no regerts......i put a .2mm shim in, just cuz I had it

Make sure your rollers are in good round shape! Lol!
Thanks
