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.

I HAD THE SAME ISSUE. CHECK YOUR VOLTAGE OFF O THE MAGNETO, IT SHOULD BE IN THE 25V RANGE. IF THAT CHECKS OUT OK CK THE VOLTAGE IMEDIATLY AFTER THE VOLTAGE REGULATOR, I BET IT IS BELOW 14V. THE FZR IS PRONE TO HAVING THE REGULATOR GO BAD (THE OLDER ONES HAVE NO COOLING FINS AND THEY BURN THEMSELVES UP). THE BEST ONE TO BUY IS THE NEWER VERSION FROM A 1999 FZR, IT HAS COOLING FINS WHICH GREATLY PROLONGS THE LIFE. YOU HAVE TO DO SOME SLIGHT WIRING MODS, BUT NOTHING ANYONE COULDN'T DO. SEARCH FOR FZR REGULATOR UPGRADE AND IT WILL EXPLAIN EVERYTHING! I HOPE THIS HELPS! GOOD LUCK!
SOURCE: where is the fuel pump on my Yamaha fzr 1000
Lift the tank and follow the gas pipe.The pump looks like a small barrel with two hoses on one side attached and a wire on the other side.It is easy to replace it.Just remember which hose goes where.Don't put them the other way opposite.Mark them with a magic marker or some pen.

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.
