so i have a 97 katana 600 in my bike, i had an 89 engine in it it ran like crap in the low end then when it opened up it really went. now with this bike it idles rough opens up clean but then it will all of a sudden it feels like it will spark and pops and feels like a little boost it only does this when i open the throttle full. first is this possible related. the cdi was swapped with the 97 one. the bike has a vance and hines muffler, does not have a jet kit yet. the carbs looked clean when i had them apart. the coils are stock 88 ones with 8mm moroso blue wires and ngk plug boots. the spark plugs on this one are the dr8es and when i pulled the 97 ones the had a yellowish look and were dry. so the question now comes down to is it in the spark, wiring harness or carbs?
any help is great
