Had a blast and today I gained a deeper respect for the latest performance enhancements made (RB, USD forks). Creek's got plenty of various size rocks ranging from baseball to watermelon - this is terrain I hadn't encountered until now, and these forks are at HOME in this stuff.
Leave it to me to talk about an injury and I'll start babbling about the ride . . . ANYWAY . . .
Throttling up a rocky hill (in second gear and @ about 3-4k RPM, no kidding), hill starts to level out, switch to third w/ a little extra clutch and and a fistfull of throttle - YEAHHHH - the 220 jumps ahead trying to throw me off it's back. 'Course I've got my knees locked onto the rad guards, standing up just a bit, BIG smile on my face and big warcry . . . and just about the time my front wheel decides to come "down to earth" it hits one of those stumps.
My reaction was ALL wrong, I would've been fine to ride it out but instead my left leg comes out for what my feeble brain figured was for support. I stiff-legged it like you would coming down - in the wrong fashion - from a rebound in basketball. Except with a sort of twist and fling. UUUMMPPH.
I managed to get off the bike and then after a short spell sort of walked it off. I rode a little more, with much less enthusiam.
I'm walking with a slight limp. Not much pain unless I try to either straighten my leg (more pain) or squat down (too much pain!) If I'm not careful and turn or step a certain way my knee wants to buckle to the inside.
I'm nowhere near dire straights here but have some concern over the tendancy for the knee to want to buckle. Any comments, suggestions, case studies, experiences would be helpful.
I've heard the stories with the ACL and so forth, but it's not like I can't get around (just a little more gingerly). I'm probably fine just need a little reassurance.
BTW - did I say that well-modified KDX ROCKS!!??
And, ive almost got Andy talked into buying an 99 KDX 200 thats for sale localy!! He wants to buy my DR, but I like having it for a backup/buddy bike. I told him if he bought it and didnt like it, i would swap the DR for it. 
We'll see......
) and only after banging around a bit do things get a little tender. I still walk OK, just get a little fluid in there and takes about a day for it to dissipate. When my knee gave out on Mother's day I WASN'T wearing the brace, so I wear it more often . . .
