Rotten egg smell is usually Sulphur.

Yes it's definitley sulphur but why does it smell all of a sudden. It isn't a slight smell, it's vile :puke:

If you have no cat and it smells like rotten eggs your battery could be on its way out. When cell shorts it causes the voltage reg to go full field . That causes the stench. I'll bet after a short ride that battery is warm to the touch.

The battery is only a couple months old so unless it's faulty?
