Blocking off the tach drive

The plain block-off plug is listed for a roughly 15 mm cable end with a 10.5 mm groove retained by a screw, and includes an O-ring. Compare that interface with the fitted drive. The Joker plug listing also describes an O-ring groove.

The speedo gear plug

Measuring 15mm across and 22mm long, the gear plug is described as a way to keep dirt off the factory speedo drive gear. CB550K bikes of 1974-78 appear in its compatibility list, which also spans many other Honda models.

Cable FAQs

Does the tachometer cable fit the 1975 CB550K?

Yes. The black tach cable is a stand-in for Honda 37260-300-000 and 37260-449-840, comes from Japan and names 1974-76 CB550K bikes in its compatibility list.

How long is the speedometer cable?

From one end fitting to the other it is 38.5 inches. The cable is black, made in Japan, stands in for Honda 44830-425-870 and covers 1974-78 CB550K bikes.

Why fit a tach drive block-off plug?

These plugs are described for removing the mechanical cable or using an electronic tachometer. The plain plug listing includes an O-ring; the Joker description names a groove. Compare the fitted drive and confirm the contents of the version you choose.
