Can't help you there m8, but i owned a 1997 sportster with the SE cleaner & SE ignition. just  thought i would add the carb Buell model's of that year had a very similar K&N , like same shape as sporster but it is slightly bigger and flows more air would fit under stock SE cover just would need to space it out. but would see a gain if tunned right, has a HD part # i could post if interested. not sure of price.
