hello team. this thread comes all the way from New Zealand! my first duke and loving it. A 2002 400 monster. last of the carbed ones and made for the japanese market. Had my stock pipes debaffled and straight cored. Sounds great now but have lost abit of power. Lookin for any info on suggested new jets to suit the mod. Dyno time here is expensive and trial and error eats money.
