Broken Crankshaft Locking Pin

I don't know the answer to your question, but I would like to know how this happened.

If the tip broke off clean and fell into the lower case, maybe you could fish it out with a magnet through the oil return line threaded opening.  I have a small magnet soldered on the end of a #14 copper wire for those type of tasks.  Also, you could remove the #2 cylinder and get at it that way, which would also give you a better view to check things out.  

At 1:30 into this video there is a cutaway view of the locking pin engaging the crankshaft, you can see a section of the #2 cylinder opening on the left side.

Pretty simple... I watched a different YouTube video instead of the one on this site and did not lock the crankshaft correctly. The pin was not properly mated to the slot on the crankshaft, which should have left about 1/2" of the pin still extended. If you attempt this procedure and the locking pin is flush with the case the crankshaft is not in the proper position and may snap off. Watch the video on this site and you will be fine.
