About Triple Series Carburetor Specification Data
This data from H and S series carburetor specification 1974 (US Kawasaki) and Kawasaki service hand book 1971 to 1976 (Kawasaki Motors Japan). There are slight differences but the data is very close to Kawasaki Japan standard specs. This table does not include some of the specs for European models..
