1985 Honda CB700SC · Carburetor Kits & Jetting Buying guide
The 1985 CB700SC factory carburetor data lists a number 115 main jet and number 35 slow jet. Those are a stock baseline for the specified carburetors, not a tune for every modified bike. Identify the fitted bank and its jet series before replacing calibrated parts.

The 1984–85 rebuild kit contains a bowl gasket, needle and eight O-rings for one carburetor. Jets and floats are not listed as included. The separately listed float needle closes the fuel inlet as the float rises; it is distinct from the long metering needle in the vacuum piston. Check the actual components and valve condition before replacing them.
Honda identifies the stock carburetors as VE65A, or VE77A for California, and lists number 115 main and number 35 slow jets. The pilot pack contains four number 35 jets. The main-jet assortment offers eleven sizes, four of each, from 100 through 125. Match the jet family and diagnose float, air-leak and synchronization problems before changing sizes; altered intake or exhaust equipment needs its own tuning assessment.
No. The float needle opens and closes the fuel inlet to the bowl. The jet needle sits in the vacuum piston and meters fuel through a different circuit. Match the failed component before ordering; a float-needle replacement is not a way to alter the tapered metering needle.
Honda’s number 115 main and number 35 slow jets are the stock baseline for the specified CB700SC carburetors. A different intake or exhaust needs an assessment of the actual carburetor series, engine setup and tuning results. The 44-piece kit supplies alternative main-jet sizes; its contents do not prescribe the correct combination for a modified bike.
Honda uses number 2 as the fixed reference; it is not adjusted during synchronization. The other carburetors are compared with it using vacuum gauges at normal operating temperature. Follow the manual’s fuel-valve vacuum arrangement, and recheck idle speed after adjustment.
