YZ400f 1998 pilot jets

Recommended Posts


Im looking for a place to buy pilot jets for a 98 yz400. I changed the cam timing to wr and can't get it to idle without rolling the throttle just a bit. The idle adjust is all the way in and I have turned the mixture screw out 2 3/4 turns. It has a 45 jet in it now, Im thinking I need a 50. It was yz450 exhaust on it everything else is stock. I can't find an aftermarket sorce to buy one. My local yamaha dealer parts dept is no help, they want me to just order a few different ones and one should be right. They don't like dealing with the old bikes.

Thanks for any help
