100 MM

Suggested at 100 MM which is about 3.9 inches. You can mess with it if yu want to change handling to your taste.

thanks

I really appreciate the help. I also called Jeff Fredette today and he told me for my weight and ability and the fact that it is a bone stock bike that 3.75 in. would be best for me. I will try both and see what works best for me.

So proper sag on a dirt bike is ~100mm...

Do you start the measurement with the suspension supporting the weight of the bike, or completely unloaded? Is the 4" sag for the weight of the rider, or the weight of the rider+bike?

Thanks,
TSG

Sag

First you put the bike on a stand and measure from center of axle to a fixed point on the rear of the subframe somewhere, record that measurement, then sit on the bike centered with full riding gear and have a friend measure from center of axle to same piont you preveously measured to, record that measurement. Now subtract that measurement from the FIRST measurement ant that is your sag. If your sag is 118 you need to adjust the shock spring adjusting nut down to put more force on the spring thereby reducing your sag, do this till you reach a setting of 100. The procedure is just the opposite if you have a setting of 80, you then would adjust the nut up reducing the force on the spring. GOOD LUCK:)
