To go back to the start of this thread the type of grease gun needed depends on the type of grease nipple fitted…. [ Guests cannot view attachments ]

The 350/4, 500/4, CB750 (up to about the K5), and other earlier Hondas used an earlier type of grease nipple fitted in the ends of the swing arm pivot bolt which was effectively a simple domed head with spring loaded ball in its centre. This type of grease nipple requires a “push type” grease gun (Mine is labelled as being made by Kennedy) to insert grease, relying simply on pressure between the concave end of the grease gun and rounded end of the grease nipple to achieve a seal. These type of nipple are often damaged due to people using hammers to knock the pivot out when removing the swing arm, or chewed up by attempting to use the more common pistol/lever type grease gun with its claw like adjustable fitting to get grease in to them. I have never had much success trying to use the pistol type grease gun to lube this earlier nipple type.
The later more commonly recognised grease nipple type (400/4, 750/K6, 750F, etc usually found somewhere on the centre on the swing arm behind the engine) is the one that requires the pistol type grease gun for which the grip of the gun’s end fitting can be adjusted to improve its seal on to the nipple.
