I was going to my buds house to ride earlier when i noticed my bike was popping on decel alot. So i turned the fuel screw out a lil, and it fixed it. Well about a half a mile down the road it started to tighten up.As soon as i felt it i pulled in the clutch and killed the motor.I look down, and my oil drain bolt(left side)is gone(with oil still pouring out). I always use loctite so i have no clue how this happenend. I took it home, and disassembled it, and found that everything is fine except for the exhaust cam journal has some slight scarring to it. Is there anything i can do to get this thing back running?I was wandering if i could take some 1200grit sandpaper to it to smooth it out. I know it sounds crazy guys, but im broke as a joke right now, and i live to ride. Please help me out. Im beside myself:( I know the pic kinda sux, but its the best one i could get. Im not to worried about the exhaust cam since i can get another, but i dont have the money for a head.
