I've been looking into doing the clutch actuator arm mod to help ease the clutch pull on my YZ426f. I read the how to article on here and it makes mention of using the YZ400f clutch arm which is already 5mm longer instead of cutting and welding. I can't find any year specific info regarding the interchangeability of the YZ400f clutch arm and the YZ426f clutch arm. On ebay they look almost the same, I contacted a seller and he quoted the YZ400f clutch arm he had would fit '00 YZ426f. I have found a post referring to using the YZ400f clutch arm on a '01 YZ426f. I haven't found any mention of it fitting a '02 YZ426f. Anybody know if I can use the YZ400f clutch arm on a '02 YZ426f? Thanks.
