Topic: Piece of PVC pipe in CB605 forks - why?

[Wildman]

I pulled off my forks to rebuild and at the top of the springs there is a small (~ 3/4") length of PVC pipe in each one.  I have an '82 regular CB which has a Vetta fairing.  Did someone put these in there to compress the springs more and make the forks more agressive?  I've only owned it for a year so I don;t know the history.

yep,firms up the action of the front end.

I can beat that one. 5 weeks ago I picked up a 1965 Honda Super 90.
I noticed the front forks had no compression to them. I tore into it.
The forks had been filled with dirt. Yes DIRT..

Needless to say. Those forks are trash.......

Yipes!  Makes my PO (who I've cursed many a time) seem like a genious.

In the Progressive Suspension fork spring kits they include those little sections of pipe to get more preload on the springs. Some bikes require them, some don't.

Interesting!
I pulled apart a pair of 750 forks and found two 3/8 drive sockets in there to preload the spring.
The amazing part of the story is that I actually needed one of the sockets for another job, a few days later.
