1.5 shims yes, gold spring probably not. You would be fine with a purple. YouTube has a bunch of videos for the yamaha clutch mods .

If you can get a helper, remove your secondary and use your back tire / rim to compress the spring. Set the secondary on the floor and lay your tire/rim over the spring centered in the rim hole. I put my knee on the tire then push down on the other side with my hands putting my body weight on it . I then have my wife remove the retaining nut . Reverse to install new spring. I’ve done 4 this way and it’s pretty easy and free .

The weight in grams is for each roller ( we call them weights) So factory stock is 8 rollers at 30 grams each.

Most up grade to lighter 18 or 20 gram rollers / weights. This is an easy mod that helps wake up the 700 Kodiaks alot

Yes doubling up shims is fine. I buy my weights from my local Yamaha dealer as they are high quality and reasonably priced.

I'm not a big fan of changing everything at once, I would suggest you do weights and shims first, you may be perfectly happy just with that.....

I recently installed a purple EPI spring and wasn't happy with it. I removed a few days later....


Just to add some background, I was already running a coop45 machined sheave and 18 gram weight BEFORE installing the EPI purple spring. In my case the factory spring works better with my 18 gram grizzly weights

Side note.

I already had my coop45 machined sheave and 18 gram weight before I tried the stronger purple spring.
what didn't you like about the spring if dont mind me asking? would you happen to have a part number or link for the weights by chance?

Just as a reference, this is a perfect example of everyone having a personal preference when doing mods.
I too have a machined sheave age 18gm grizzly weights, but for me, I love the purple epi spring, back shifting is spot on, and engine braking is amazing with this setup.

As Vincent mentioned, try things gradually, you may like a different setup. Some prefer the 20 gram weights, some even do 4x 30gm and 4x the lighter grizzly weights staggered, it's all personal preference.
