Has anyone here ever experienced a K5 magneto failure on a known good running motor?

Subject Bike is my 07 KTM chassis/99 K5.  

After much work by others/smarter people with a timing light on the bike and it being rotated with a drill motor the timing would jump +/- several degrees randomly.  Stator checked out as well as CDI, coil wiring, plug.  Turns out a swapped out new magneto fixed it.  Again,  I had a ton of help from some very great people to get me going.

The strange thing is that the bike ran fine before this issue.  I understand that magneto rarely fail but this one sure did.  It runs now and is a lot of fun again.

The up side was I learned alot from several good guys thru this process.  The failed part is actually being cross sectioned to look at the internals.  I will share any data I receive.
