Lordsir here. Long time reader, first time poster. I have a '94 GSXF 750 USA non California model Katana. It runs pretty rough. When I measure the temp of the header individully with an infrared temp meter they read as follows-
#1:200-250deg.F #2:200-250deg.F #3:70-90deg.F #4:500-600deg.F
I have checked the spark plugs, coils, coil wires, ignitor, carbs, and battery.
I am at a loss as to what it could be. With the bike running i can pull the plug wire for the #3, #2, or even both at the same time and it does not affect the engine operation at all. Which seems kinda weird to me. Here are pics of the exhaust, etc.... Notice how shinny the #3 pipe is.
Any advice would be greatly appreciated. Also I live in Oregon so the weather is not a factor.
