What color spring would be best for my 04.5 Sp600 for low end for wheelies and such. I want more torque, but don't want to hurt my top end. Thanks

 

Get a Heel Kicker clutch kit and use the orange spring in the kit. The orange spring raises RPM's before engagement, but most folks don't like the higher engagement.

If you want your 600 to pull a wheelie it'll take some work, remove heavy stuff up front (winch, brushgaurd) and mod the intake/exhaust for tourque (800 header,800 intake snorkle & rejet). It can be done but your machine is made tough like a tank and tanks don't wheelie.

 

Put a Heel clicker in it I got one and I can pull wheelies in high range but I also have more mods. Click here for wheelie pics.

 

Haha nice. Lokos like fun doing that in High range. Do you have the Heelclicker spring that comes wiht the kit in it?

 

Yes I have the orange Heel clicker spring in the primary.
