yz400f/yz426 engine harness the same?

[guggi102]

Are the 400 and 426 wire harness interchangable? How about CDI and other electronics?

Im not posative but im pritty sure they are. Their almost identicle motors other than bore and the valves as far as i know.

yes, they are the same. wr has extra stuff for lights, blinkers etc.. but that will work also, just have to tuck that stuff away.
