I agre with DUALSTROKE.
You can do is, to try it yourself, start of by setting youre springs, wich in Blaster cases is usually all the way up... usually...
Then try out rebound and compresion, try out each one on full adjustment to hard and soft, understand what youre dealing with first, then try out diferent setups by doing some laps, carfull when riding dont forget you are "playing" with the suspencion, so some setups will be real strange....
Go ride and have fun while learning... thats the secret of a good setup.
Have fun
Hope this was helpfull.
