Ok, I think I have found the source of the folk knock. After my thread http://www.cafehusky.com/threads/front-folks-to-stiff-stripped-down-and-discovered.81426/ my folks where much better but still a little stiff for my liking. Not happy with this I pulled them out again to see if I could improve them. The first thing I notice is my right folk has stiction...push it in and on return it will "hold" and then rebound. This got me scratching my head, why?? and why the right folk more so?? As well as this I notice a very slight tight spot about 50mm down. In the pics below you can see there are two black circles on my right cylinder and this coincides with the tight spot. A bit of hand reaming (see below) and the tight spot is now gone, great!. But with the springs out of the Stanchions theres still stiction on "change of direction"..why?? Well its pretty simple.....see the shiny spot (looks black in the picture) on my right Stanchion (caused by grit and so forth getting caught under the dust seal) on the picture below....I have been told this is no good and to get a Scotchbrite and rub it off using a helical motion. So I did just that to the entire working surface and the stiction reduce straight away, great!. The next thing I did was add a some folk oil and lithium grease and behind the dust seal and viloa, the stiction is now gone! I repeated this on my left folk and it has made a huge difference to the responsiveness of my folks. The real good thing about this is you can do all of this on the bike.
1. Remove the stone guards
2. Place bike on center stand
3. Scotchbrite both Stauchions and clean off
4. Slide dust seal down (I used a piece of Pine timber with a square edge which wont bruise or damage anything) behind the outer seal edge and tapped it down gently.
5. Add a few drops of folk oil behind the dust seal and reset the dust seal.
Our folks are just to dry, now yours should feel better and if like mine the knocking should have gone.
