EPI clutch spring help

[Riven]

Last year I put an EPI Sport Utility clutch kit for stock tires on my 600 & it was a great mod but now with the 27" Mud Machines coming I am thinking I might like to upgrade to the oversize tire clutch kit.
Can anyone tell me what the difference between the two kits is?
Will I just need a different spring or is the helix also different.

Thanks.:)

the difference between 26" and 27" shouldn't even be noticed. the only thing that will change is that your going to a more aggressive tire.

i ran my 29.5's with a stock clutch and belt with no problems. did it from the day i bought the bike until about a month ago.

i would say leave it as is and see how good it does.

if it aint broke dont fix it.

I was only the more aggressive tire that was my real concern, but are right I will give it a try first & them change if i have to.
