lately on my 99 xc sp, i've noticed it bottoming out when it shouldn't be. my brother also noticed this last weekend. i weigh 160 lbs, and he weighs 180, so i think it should be able to handle some mild approaches. i have the 'block' set to the stiffest setting, so i was wondering what else i might do. with the fox shocks in the rear, the owners manual says to get them revalved stiffer. i don't want to spend money to solve this problem, when it doesn't seem like it should be happening in the first place.
