SOURCE: 1994 yamaha fzr 600 spark plugs foul after about
Really...strange what you need to do is see if the bike is running too fat. So...warm her up witha fresh set of NGK! spark plugs. After the bike is warm take it down the street and back. When your on the way back get on the throttle and accelerate then shut er down and coast it into the garage. This will give an acuurate read on the spark plugs at operating temperature and under a load. Pull all the plugs. If they are brown like coffee with cream that means carbs are adjusted correctly. If they are black and wet too rich and if they are white or very light brown too lean. Other problems may be oil soaked plugs from loose top end parts. Maybe valves or guides.

No one thing controls those items.
The ignition and headlight circuits
each have their own fuses under the seat.
If you have power to both of the coil sets
then the coil for cylinder 3 and 4
might be faulty.
Lights may just have a blown fuse.
You have more than one problem
going on there.
