Barrels are hard to source now, I sold my last set a few months ago. I have only ever used stock carbs so I can't really advise there but I am sure some of the chinese made one would work but you would probably have to cheange some jetting and or do some modification to the mount etc. Don't forget the airbox is different too, as is the baffleing in the mufflers and the collets that screw on to the barrels are a different size. There is plenty to consider. Chris
