Hi all,

I have just stripped a fiends forks on his 1991 (ish) K1100RS.

He has owned the machine since 1994, and has never had the forks apart.

I have found one of the snap rings (on top of the seal) to be broken in half. No problem there, just fit a new one.

However, having removed the dampers I have found one seems to have a lot of up and down play when it is fully extended as if there is a bush or rubber 'O' ring missing. It also doesn't seem to have any resistance when pulled in and out, compared with the other leg which while offering minimal resistance, does does emit a 'fart', especially if the holes on the chamber are covered.

One other question. Given that I have stripped it down and cleaned out all the sludge, should I now fill both legs with the same amount of oil?

Regards

Mike

Cheers Inge,

I thought as much, it was a little vague in the manual. Any idea on the damper cartridge question?

Hi Inge,

Thanks - Blimey a K question you can't answer Laughing

Yes, I was aware of the different dampers, and made sure I kept the parts associated with the correct leg.

I have refitted the dampers, and am just waiting for the new fork seal retaining snap rings to arrive from Motorworks (hopefully today) to complete the rebuild.

The guy who owns the bike is a bit on the large size, but said that he thought the forks were working fine before the seals needed replacing. The chrome on the fork tubes still looks very good, as he fitted gaitors years ago. There was some crud in the legs, but all cleaned out now.
