I'm dealing with a box-of-bits KZ440A1, and am in the process of putting it all together. However, I've hit upon a snag. Wondered whether any of you guys might be able to shed some light on this? I'll describe the issue.
Fork caps: standard screw-in chrome fork caps. No problem. I unscrew them. I expect to find, underneath, a slider/spacer (part number 44029022 as per the parts diagram) held in by a circlip. But I don't! Instead, there's a second fork cap there, underneath. The second fork cap is black, it's also screw-in (uses the same thread as the shiny fork cap tops) and has a square indent for a 12mm-ish tool to wind them in and out. A 1/2-inch drive wrench fits in and lets you screw them out and put them back in again. Underneath this secondary fork cap there's just the fork spring.
Problem is, one of these secondary screw-in caps failed on me (I was probably putting it in not quite square), and has now stripped its thread. No matter, I thought, I'll look up the parts diagram and buy another one. To my surprise, no parts diagram for KZ440 shows this part. I looked up the KZ400 parts as well. Nothing. Same as for KZ250. The standard bikes, according to the parts diagrams I accessed on cmsnl, appear to all use a circlip-and-plunger arrangement under the main (chrome) fork cap.
Now, I was thinking, if I reassemble both forks with the standard plunger (without circlip) plus a spacer, and rely on the topmost fork cap to hold it all together, it would probably work. But I'd rather not deviate from the manufacturer's design, especially as the topmost fork cap isn't designed to hold down the spring pressure.
Does the fork cap arrangement I've described ring any bells with anyone, and if so, have you any pointers as to where I could get one of the little internal screw-in fork stoppers to replace the damaged one?
Thanks
