ok,well, i thought they were all intake too, but turns out the hose attached to the metal pipe is a little exhaust outlet. I unscrewed the pipe and stopped the hole with aluminum foil and used the same screw to keep it there and im just hoping that wont cause problems, i assume the exhaust will then find its way to the right pipe... i could be wrong tho. But as for the crankcase, he gets a breather and the little metal piece on top of the carb boot gets a rubber nipple. Add your K&N filter and you're good to go. Oh and the "EPD" its a just a little rubber reed covered in 5 pounds of metal, its stupid, so i threw it in the garbage
. I just took my first test drive and it feels good except maybe a little weak on power. But i have no previous experience riding the zong, it could just be a weak bike. It feels like the clutch isn't fully engaging until i hit the higher rpm's. I have 10w40 in it and i live in miami, that shouldnt cause slippage right?
