Suspension tuning class

You could go to the class and I am sure you would learn something. Have you read the manual yet? There is a lot of good information in there. Start with:
Springs control height. That is all they do. There is a minimum and a maximum spring length. Have you checked yours?
Check and set sag every time you ride.
Static sag, race sag and check height with the bike on the stand. The manual will give you the proper measurements.

Check air bleed with the bike elevated every time you ride.
Change the fluids in your suspension on a regular basis.

Starting with fresh oil in both ends. Set the sag and set the settings to stock settings.
Take a out lap and a hot lap. Time your lap times. Adjust the suspension valving in accordance with the track. Balance compression and rebound for soft to hard. Too much rebound can make the suspension feel hard. Too little can make the suspension feel hard.

Proper springs for your weight will make your bike feel like a new animal. If you are too heavy or to light you may not even be touching the valving where you need to.

I suspect a lot of what they will tell you for $99 will be the same thing here. Suspension isnt a dark magic kinda thing, its a constant that changes daily and track to track. Make notes of the day you liked it, and you didnt. How many braking bumps were there. was it wet or dry, was it hot? The guys in the factory semis that know suspension only know it because they have a standard to come back to. When you finally get what you want, fine tune with valving and oil weight.

Good luck, it can be your best friend or worst enemy.
