Fzr6 running lumpy
il try n help m8,, can i start by eliminating a few things,, have u made sure all 4 carb floats are the same height ,they need to be, ,and there is no holes in the diaphrams at the top of the carbs,,even a pin hole will give u grief,, ,,wot happens wen u pull the choke out wen motor is warm and idling,, if it evens out and pipes warm up then theres a blockage in 3 and 4 carb,and idel jets,or could have a split vacume pipe, or a air leak between the carb and cylinder,,if all fuel symtoms are ok ,, then make sure the coil wires are on properly, and good spark on the coolest cylinders, , try swapping over the coils to to see if the left cylinder becomes cooler than the right,,hope that gives an idea,,
