 |

Watching my forks while driving, I'm down to the last 1½" of travel. With 64k on the clock and being cheap, I was think of 1" spacers cut from PVC pipe. Has anyone tried this?

Can I suggest that you spend more time with your eyes on the road ahead 
BMW forks are notorious for their long travel and soft action.
On my R100 RS Mono, I spent $2 on a bunch of M8 stainless penny washers. From memory they are about 3mm thick, and I used 6 or 7 on each side.
This makes it easy to fine tune your suspension, and you can still change the fork oil through the upper fill hole

OK, somebody tell me what I'm looking at.
Are the springs about 35mm in diameter? Does this whole assembly lift out or do I need to remove what looks like "keepers"? I couldn't lift it with needle nose pliers, only rotate.
I can't see where 8mm (hole size) washers would stack up, unless their OD was about 32mm.

The stock springs are 30mm inner diameter. You would have to compress the outer part to get the dogs/keepers out. They'll lift out with a magnet.

Mike - have you got the forks off the bike? If not be careful with removing the collets (dogs/keepers) as they hold the push rod in place, without these the rod will slide into the bottom of the fork!

I put it back together. I'll try the proper amount of 10w oil tomorrow.
