i have a 1975 (76 motor) cb550k. the plug wires which are permanently attached to the coils are mis firing. the wire on the #4 cylinder has a bulge and thin spot on it and the cap seperated from one of the other wires. i have reattached the cap but what i am wondering is if the #4 wire can be spliced some how as the price for a new coil/wires is about 160 dollars. also it runs horrible in hot humid weather, like its running on 2 or 3 cylinders, hardly has power to pull from a light, cools down and its better im thinking its getting too much fuel and there is hardly any vacume (suction) at the carb inlets. this bike looks great ive done lots of cosmetic work polished the entire engine ect but i need it to run right. its abit noisy in the top end, maybe a cam chain adjustment? valves? could the coils run hot causing it to run rough? i dont know and dont have much money to let a mechanic guess at it.
