basic re-build kit for each carburetor (float bowel gasket, needle/seat, o-ring for idle mixture screw). o-ring for idle mixture screw is slightly larger than Yamaha part. does not come with carburetor connecting tube o-rings (8 required), they must be replaced if splitting the carbs, or the carburetor connecting-tubes leak gas. also, the center "t"should be replaced with after-market brass one. stock one is nylon coated steel. the nylon shrinks with age, and leaks.
it is a good basic kit comes with needle valve assembly drain screw o ring , the mixture screw o ring is thicker than oem o ring but is still usable as replacement
Satisfied very good kit. The picture tells it all for me that it was authentic Japanese parts that I could trust to fit my carburetors and the price was good as well.
