Looking at my k3-e model and have a query about the 3x3. I'm a bit confused, William1 said to remove the snorkel and stick a 158 main jet in - got my jet yesterday and whipped the seat off....there is no snorkel (that i can see)and the hole in the top is definitely standard but measures approx 3.5"x3.3". is this coz its an e and not an s/sm. (only everyone seems to have to cut the hole bigger!) as far as i'm aware the jetting is standard atm, and i still have stock e exhaust. should i tape it off to measure 3x3 or what? Thanks in advance.
