Here is my sad, sad tale. Hopefully somebody at TT can help me at least figure out how sad it really is... I'm out for my 6th or 7th ride on my new '05 WR450 (less than 200 miles on it) and having a serious blast with my ridin' buddies. We're riding up this semi-steep, yet deep sandy climb. Near the top, I hit one of the only sizeable rocks on the whole climb and bucks me off. The bike squirts forward and hits the only other rock on the whole hillside. No kidding. Anyway, I go to pick up the bike and oil is GOUTING out from the crankcase area just adjacent to the shifter arm. Uh Oh. Anyway, we break the chain and tow back to the truck. Now, I've got a missing chunk of crankcase (about an inch diameter) just below where the shifter lever enters - it's as though the shifter lever torked DOWNWARD (think way overzelous downshift into 1st gear) and blew off part of the crankcase. How screwed am I? I can send pics to any gurus who might give some advice, but I'm not sure if I can post the pics here. Any advice or thoughts would be welcome.
