YZ400f 1998 pilot jets

Hi

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

did you have the slide out of the carb?

no, have only taken off the bowl.
