Hey, I just got a 2001 lc4 enduro w/ 1000 miles on it. Stock everything, I think. Anyway, whenever I hit a jump, large bump, or some whoopdies, my bike bogs down like it's gonna die, sometimes it does die. If it doesn't die, it takes about 30 seconds of throttle fussing to bring it back to normal(throttle fussing=not riding, just keepin the bike running). The only thing I could think of was maybe the PO chopped those springs inside the carb, but I haven't taken that thing apart yet. Any ideas?
