I have a stock (I think) Blaster rear shock and I have the preload as soft as it goes. I weigh 190 I think it could still be softer, but i don't do huge air jumps, just lil' hops for my blasty. It may be not a stock shock. Heck I just found out it had banshee rear wheels and hubs. How can I tell if my shock is stock?> Thanks!!
