Well Drew is the expert, I could very well be wrong. I did notice that when I ordering parts a few times I wrote them down here. I can't remember if it was jet kits or rings or what. But in the computer at the Honda shop they showed up as discontinued..

Then when we found the parts in the fiche catalog they came up with different number, as newly made parts.. Maybe it was pistons? Or maybe I am just a moron.. Drew seems to be a walking encyclopedia of parts nomenclature. He I will claim ignorance and blame him for everything
