Honda 400ex stock jet sizes??
 

Can anyone tell me the stock jet sizes for the Honda 400ex? I have an 03 that I moved up jet sizes on to go with the White Bros slip on. I have gone back to stock exhaust and want to go back to stock jets. Anyone know? The local shop had a female answer who thought I was talking about a fricken F-16 or F-14......ugh.....

I am going away from it. I loaned it out to a buddy and he blew up the White Bros E2 Series. No idea how he did it. But I went out and bought a 08 Raptor 700 and I was just putting the stock exhaust back on instead of sinking money into it. Weird, I thought sinking a couple hundred into it was too much....so I went out and dropp $8000 on a new quad.
