1975 Honda CB750K · Fuel System Buying guide

Choose the tank fittings and carburetor repair separately

The 1975 selection pairs an M20 × 1.5 replacement petcock with a 1975–76 reproduction tank. Carburetor choices range from a one-carb repair kit to four-piece holder sets and separate airbox components.

Choose the intake parts for the layout you are keeping

Retaining the airbox calls for the stock-type filter and the appropriate carb-to-airbox boots. The holder set is a different purchase from those boots. Identify which rubber connection needs repair before combining a four-piece set with individually ordered boots.

Plan a tank replacement before paint

The 1975–76 reproduction tank arrives in primer grey. Lay out the cap, latch, petcock, emblems and mounting pieces you intend to reuse before refinishing; their condition can change the order even when the tank itself is the correct application.

Common questions

What quantity does the carburetor repair kit cover?

One kit rebuilds one carburetor. It supplies a #110 main jet and #40 pilot jet; those are package contents, not a tuning prescription for a changed intake or exhaust.

Will this petcock suit an aftermarket tank?

Only use the stated M20 × 1.5 thread as a comparison with the fitted tank connection. The 1975 model year cannot identify the outlet on a substituted tank.

Which fittings must I budget for with the new tank?

The reproduction tank excludes the cap, petcock, side emblems and all additional hardware. Check which of those parts you can retain before ordering replacements.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
