Hello All,

This is a bit of a long shot but does anyone know off the top of there head the dimension of the fork spring in a KZ 305 front fork?

There's a 250/305 FSM pdf available on the internet (green cover), but the diameter won't be listed if you need that.
The Fork Spring Free Length chart is on page 152. Standard = 452mm. Service Limit = 442mm.
There's also a fork oil chart on the same page. 150cc. 440mm from the top of the inner fork tube.
note:  as per the instructions, check the fork oil level w the springs removed.
Page 112 says to install the fork springs w the smaller diameter end facing down, so that end goes in first.

Looks like 22mm OD.

Edit for clarity: 305 shares some fork parts with the 440, so springs should be same OD, different stiffness.
