How are the '03 300 EXC's stock suspenders, generally speaking? Do they benefit much from a revalve? I've got about 160 miles of desert riding on mine, and it still seems stiff, although they tell me I need 4 times that before the suspension will be broke in. I'm 173 #'s, 5'10", "medium" fast, semi-aggresive. I'll also be riding the mountains this summer.
