You need to get a new digital igniter electronic board, which is right under your seat. When it dries out with time, electrical boosts take place and burn out the sparks.

If the spark plugs are very black and sooty when they come out, then there are 4 sets of o-rings in the carbs which need to be replaced. Also if the float heights are set wrong, it can cause this. Hope this helps :)
