Honda 400ex stock jet sizes??
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.
