The charging system is NOT working...  You will need to fully charge the battery BEFORE riding it the 100 miles home...  The battery's power is all you have to run the engine on.  Once that power is gone, you have nothing to fire the plugs.

The battery is being deep discharged -- this will shorten the life of the battery, dramatically.  You need to get a trickle charger on it, to slowly, and safely, bring it back to full charge.  I recommend a Battery Tender Jr., available at most automotive stores, and DIY stores, also can be ordered online, all around $30.  Hook your bike up to it every time you shut it off, in the garage, and it will likely double the life of your battery (will work on any type:  flooded lead-acid, Gel Cell, or AGM).

Download the FSM, as discussed, previously.  Then read up on the charging system, and do some troubleshooting.  Cheers!
