:banghead:Can anyone tell me where to find a rebuild kit for my 99 yz400f? I went to the dealership and they cant find one. It has a 39mm keihin on it. All the dealership could do was look on microphish and sell me the individual gaskets and seals I needed, but that would cost me about $150 dollars. There has to be someplace that sells the complete kit to rebuild my carb for less than that.. Can someone tell me a web site that would have this?
