Hey everyone, Don't know if anyone has experienced this problem; A rock punched a hole in my crankcase cover during an Enduro this past Saturday. The hole is located just forward of the straight plug. I was 45 miles into the 75 mile enduro when I discovered oil on my boots and left side of the bike. It was still running and oil loss was minimal. I figured on running it 'til it died or I finished the race. My bike ran great for 25 hard miles before it finally quit on a long uphill. It did not seize, the oil level was still adequate, it just stalled. Tried every method and trick to start it for an hour, but not even a pop. Finally, after a PBJ sandwich break, I gave the throttle 3 twists and it started for about 2 seconds. There was oil mist and forced air coming out of the hole. Long story short is that I was able to keep it running by constantly pumping the throttle to keep gas feeding the cylinder and got out. My questions are: 1. Any thoughts on why it would die after that many miles. 2. Is there normally pressure in the crankase to blow air and oil through a hole in the crankcase cover. 3. Anyone think of other problems that may result from the punched cover? Thanx for your answers and the awesome forum!
