You should have your pre-load (Spring Adjustment) set for approx. 1/3 of total suspension travel. Once the preload is set correctly you can set the damping adjustment (controls oscillation speed) to suit your preferences.
1. Go to your owners manual for travel limits of suspension.
2. On a Vstar 1100 its 4.5" rear travel and 5.5" fork travel
3. Jack the end of the motorcycle youre adjusting or the whole bike if you prefer to do both at the same time. Ensure that the suspension is unimpeded to the full extension of travel (ie don't jack by the swingarm or fork).
4. If you're adjusting the rear suspension measure from the Axle Nut to a fixed position straight above the nut. I used the lower edge of the chrome rail on the fender. If the front travel measure between the lower triple clamp and the top of the fender.
5. Take that dimension and subtract the 1/3 of travel for the rear wheel (1.5"rear 1.8" front.) So if your dimension was 11' minus 1.5" leaves you with 9.5".
6. The 9.5" is the dimension you should be trying to meet between the same two points previously mentioned, with the motorcycle back on the ground and the normal compliment of rider(s) and gear.
7. Adjust the nut on the shock to achieve this.
8. On the forks you will be adding to or removing length from the tube above the spring. Progressive gives you a piece of schedule 40 plastic pipe to achieve this. Put a washer on the top and bottom and you're ready to go.
Most bikes come preset for a 200LB rider.
