[Polaris425]

***Admin Edit*** The information in this thread mostly pertains to 2005-2011 kawi clutches.... 2012+ saw design changes and it's best to just call VJF (Vforce John). He's the best when it comes to kawi clutches.



From EPI:

Maroon (Lighter than stock. Not the same as the maroon primary)
Black (Almost same as stock)
Almond (Good for 27'' and lighter 28'')
Green (Good for heavier 27'' and all 28" )
Lime green(Good for heavier 28'' and maybe 29.5")
Red (Perfect for 29.5'' and the lighter 30")
Yellow (Good on only 30'' or larger most aggressive tires)

From VFJ:

#1 Gray/white
#2 Orange/Purple
#3 Orange/silver
#4 Gray/Red

And while your changing springs, if you need to add/change shims for belt slack, these are the available shims:

Spacers
Part No. -------------Thickness
92026-0034 --------- 0.3 mm (0.012 in.)
92026-1569 --------- 0.6 mm (0.024 in.)
92026-1617 --------- 0.8 mm (0.032 in.)
92026-1565 --------- 1.0 mm (0.039 in.)
92026-1570 --------- 1.4 mm (0.055 in.)

Can you give us a primary spring rundown too?

 

[Polaris425]

Wes?!?!?!?!?

 

[cigaro]

Well.... the primary is hard to set in stone as far as tire size goes. So many variables effect what primary you might choose. Rider style, engine mods, whether you're trail riding or pit racing are just a few. This is where buying/trading springs and test them comes into the play.

 

[josh13]

Ok, these are all things I needed to know. Thanks. I like to ride with lots of power down low or any time I need it. top speed really ain't much of a big deal. As for mods I got a moose module, just ordered a 6* key, stock exhaust mod, snorks soon, probably a new filter, and 27" or 28" zilla's on steel rims soon. Any suggestions? Thanks.

 

[Polaris425]

I think you'd like the maroon primary too... It's what I have.

 

[josh13]

Where is the best/cheapest place to get springs? And should I get a kit or just springs?

 

[Polaris425]

just get springs, you can order them direct from EPI

 

[josh13]

Sweet!! Thanks.

 

[josh13]

I found these on ebay. Said to be 3 red, 1 yellow, 1 pink, 1 white, and 1 blue. Not sure what brand yet. I think what they say is white could be almond? Input anyone?

 

[phreebsd]

huh unless the chinese are making off brand springs, they're either EPI or Dalton.

See those two red looking springs. They have the end wire sticking up on the top and bottom. That's not going to work in a brute.

here's a spring chart by Metal Man!

[Polaris425]

yeah I'd stay away from that... EPI isnt expensive. I ordered 2 springs, and a primary clutch tool and spent $75... including shipping. $35 of which was the tool.

 

[josh13]

Thanks for the chart. The springs are listed as polaris and kaw cvt springs. They are going to sell pretty cheap I believe but if I can't use them I wont buy them.

I just heard back from him and they are stock springs. Not even going to think about it, now for sure.

 

[josh13]

Ok, so let me get this right.With 28" zilla's/steel wheels, moose module, 6* timing key, exhaust mod, an air filter and snorks, I should run a maroon primary and almond secondary? Sorry about being repetitive but I want to get it right.

 

[Brute650i]

sounds good I had 28 mudzilla's with moose module and green secondary and thats it and never had any problems

Yes that will work fine. I have run that setup with my 28 zillas and liked it.

If your super concerned about top speed a stock secondary from a 750I would work as well. The EPI almond is a little stiffer then the 750I stock spring thus giving a little better grip with a touch lower top speed. Both will work great.

 

[josh13]

Top speed is no big deal I want TORQUE!!!!!:flames:

 

[zillabrutis09]

how

how do you read that chart that metal man put up?? the 2 2 1/4 thing and all thanks

 

[cigaro]

It's reference to compression length. It tells you how many kg/ lbs of pressure it puts out at a given length. This helps you determine the stall, shift rate and top operating rpm.

 

[KMKjr]

So if I have a stock 06 BF650i, with only 26" tires, should I waste $$ on spring(s) or wait until I put in a CDI, etc....
