Sparks and flame out of breather

[wraith]

OK, never seen this before... Started the gsx1100f powered Kat up just to keep it happy over winter. Been outside, under a nylon type bike cover.  (I have the braided hose and stainless mesh filtered crank case breather up between the outside of number 4 carb and cam cover).

Wheeled it around a bit, including sitting on it, no static noticrd. BUT - When I pressed the start button I saw a spark go from the outer upper side of the cam cover to the breather filter and that then gave a small flame.

It has a Dyna 2000, Dyna coils and ht leads.

Not started it since; suppose I ought to, but..?

Any ideas what it was, or has anybody seen this before?

could the ht lead be shorting accross a wet cam cover surface ? a film of condensation over the metal and the lead be sat in a drip of water, a nice hydrocarbon vapour mix built trapped in the breather filter ? the bike will be fast, its eager !
