hey guys, I have a 2002 400ex. I was gonna put the sparks key in, but the guy i bought the quad off of said he thought the rev box wasnt the stock one. I want to make sure it isnt one off an xr or something which would already have the timing advanced. Can someone please tell me what the white numbers are on the side of their stock rev box so i can check it? thanks!
