Well at least you know what is wrong with it now :-)

Looking at it closer you are right the magnet has slipped out of it's mount and is blocking the path.

Is that where all the filings came from? Is it actually magnet?

Yes the filings are ground up magnet. I wish I could have just replaced the magnets because the module tests fine. I bought a new 2Ki module this afternoon for 190 and a new rotor for 9 with free shipping.

I'm debating splicing the new module into the existing wiring instead of rewiring everything.

I've seen this before. Usually the bolt comes loose and the cup starts "machining" the module. If the cam has too much end play this can also happen!!

Update:

I put on the new module and rotor today and once I found TDC it fired right up. The first time I found TDC, it didn't leave me enough movement in the module to use the bolt holes. I spun the motor around a full rotation to the next time it hit TDC and then it worked. I didn't use the VOES or tach wire so it was a simple 3 wire hookup to the coil and done.

Tip for the day: If you need to replace the rubber bushings for your gas tank brackets, Tractor Supply has grommets that fit perfectly with a little trimming. About a dollar a piece.

This is because you should flip the pushrod tower keepers and check that it is the compression stroke TDC (both valves shut, pushrods will spin) and not the exhaust stroke TDC (pushrods will not spin) at the exhaust TDC the valves are open so that the exhaust gases are expelled and the inlet is starting to open so it can suck the new fuel charge in.....the valves are considered to be "on the rock" at this point.

On a four stroke you only get a firing impulse every other TDC.

If you have the VOES hook it up. If you don't have one, get one then hook it up!!!

Is VOES really worthwhile to have? (my bike was EFI, converted to carb). I never hooked up a VOES switch (was extra cost @ the time when I did the conversion...didnt have the extra $ for the sensor). AFAIK, with my dyna ignition, all VOES does is ramp the timing faster (or slower) based on vacuum. I can accomplish the same thing by either grounding the VOES wire, or leaving it disconnected (for either slow ramp or fast ramp)

The VOES is needed for correct timing at slow and high rpm's.

The VOES can help prevent detonation under a load which your engine would appreciate very much. The cost to benigits ratio makes it a great deal. Hope this helps.
