Description
Get your vintage Honda SOHC four idling smoothly again with this genuine Keihin pilot (slow) jet, the correct long-thread OEM style used in early-to-mid 1970s round-slide carburetors. This solid brass jet measures 28mm overall length, 5.5mm outer diameter, 3.4mm thread diameter and 2.0mm tip diameter, matching factory specs exactly.
This is the older, threaded "long-thread" style Keihin pilot jet (28mm overall length, 5.5mm body diameter, 3.4mm thread diameter, 2.0mm tip diameter), not the later push-in style. Honda switched carb designs on the CB550 and CB750 in 1977, so buyers with a 1977+ model need to check they actually have the older threaded-jet carb before ordering, otherwise this jet won't fit. It's worth noting these are very similar in profile to Keihin N424-24 jets but shorter, which is a common mix-up point when cross-referencing
Fitment Range
This jet series fits a broad span of vintage Honda SOHC fours: CB350F (1972-1974), CB400F Super Sport (1975-1977), CB500K (1971-1973), CB550F/K (1974-1976), CB750F/K (1969-1976), and CB125S (1973-1982).
Notice
Before You Order — Measure Your Jet First
Remove the jet from your carb and physically measure it. If it does not dimensionally match this listing, this is not the correct jet — do not buy it.
Buyer is solely responsible for confirming the correct jet size before purchasing. Do not rely on year/make/model fitment guides — they cannot be guaranteed 100% accurate.
All jet sales are final. No returns or exchanges — no exceptions.
