250 99 KX250 Carb Rebuild Kit????

So I am trying to find a Carb rebuild kit for my bike. It has a Keihin Carb, but when I look up the part number I can not find anything on it. Does anyone know where I could possibly find a rebuild kit, or any information about? I have attached a pic of the what I believe to be the part number, the other side just says the brand.


Those ‘98+ KX250 are awesome bikes. Maybe the brakes and forks are a little mushy but I had a couple and really liked em. Never felt as comfortable on any other bike. I thought I could get away with anything. Which.. had me doing some pretty stupid crap lol
