hi ben600......caps and plugs.....you have two coils on the fazer one feeding cyl 1+4 and the other feeding 2+3....if your running on 3 it must be the cap or plug,even more so if it only happens in the wet.....could be the ht lead but very unlikley....best to replace all four but as already said you can identify which cylinder by carefully touching the downpipes 
.....let us know how you get on
