wis is right, its the rebound, try playing with the clickers and then try it again spend a hour on tuning your suspention it will go a long way in to making you alot faster, and way eaiser to carry speed through bumpy area, suspention is the most overlooked performance mod you can do not to mention it also makes you a bunch safer! i know what ya mean about being thrown when the rear packs through whoops, your just going along for the ride!, had that same thing happen to me, then i did my suspention, adjust ride, adjust ride, adjust ride, until you figure whats right for you, also be sure to check your race sag, it should be 4" if its not adjust the spring until it is, its near impossiable to set the clickers until the sag is set correctly, good luck have fun, you will be suprised how much smoother your bike will feel.:scream:
