Primary shims made easy with pics

[stingray719]

Remove clutch cover

Here I have one Yamaha shim (1mm) and one shim from Bender Racing (6mm) and the pair comes out to 0.27inches according to my caliper. I advise starting at 2mm or 4mm and increasing by steps. Shim from Bender Racing was $9.95

Put shims in the cover, the first pic is for illustration.

This pic is with the shims in.

Put the spring on and install back on the primary,

BUT, make sure you line the X up on the cover and on the clutch for balance.

Enjoy!!!!!!!!!

Does Yamaha have a 2mm or just the .5mm?

I had to go to a vendor for the 6mm shim. Vendor is not a paid vendor here so I cannot name but a quick Google search brings it up

That caliper reads .270 inches or 6.858 mm.

OK so now that we have the caliper reading out of the way, the looming question is this: Do you actually run 7mm of shim in your clutch?

Girlfriends all stock but clutch has 7mm, my tricked Viper is running 6mm . Anything 4mm or north of it works but found the best results 6 or 7mm

Now how do we boil that down as elevation drops away? In other words probably a better question is what does Terry run in his?

why not go to a stiffer spring with the same preload?
g/w/g .....45-136
why not jump into a p/g/p 40-139
or does the shim allow you to adjust the pressure in smaller increments?
I run a single shim in my primary just to get the extra 50-100rpm I wanted

Tried the orange/silver/orange 35/143 but it was a little shorter and did not work for me. For some reason this clutch likes the long spring shimmed. Find a better solution cheap I am all ears.

Terry has the 2mm if I believe. As I tested I kept increasing mine and quit at 7mm I advise starting low and increasing.

It's ok everybody makes a mistake sometime. We knew what you meant.

BTW, I put my shims, weights and springs in today. My clutches had some pretty good marks in them from where the engine was just overpowering the belt. Hopefully this will make the difference.

Ok so awhile back I put on a g w g and wanted to shim it also but never could find a shim for my sled no matter who I called most of the dealers up this way didn't even know what I wanted one dealers said they found them and they would order for me, perfect. Got them in and they were the belt adjustment shim wtf. So if someone could tell me where I can get shims I would appreciate it.
