What are the advantages? More torque,
top speed, low-end power?

I am looking into upgrading
my clutch with wanting to go
to with 27" tires for my 450.
Not now but maybe during the
summer, I still need to get past
my plow system install, finished
mounting the frame plates today
(first steps) along with radiator replacement
(another thread), anyways was just
curious about this whole primary spring
upgrade, cool thread!

With waht you are wanting you can get with a spring and dialing in your secondary but witht the time involved you would be better off getting a kit for big tires.It could take many many hours to get it dialed in.

 

Ftwflh -

I was more or less leaning
toward buying the heelclicker
clutch kit for my 450 anyways.
I need to cool it right now, with
all of my spending. Yea Yea I'm
married, wife complaining, I've
been on an extended Christmas
spend.
