  2. Success! The damping is much better, and the adjuster screw has a greater effect on the range. I used 5w, but in the future, the fork could easily be tuned with a more viscous oil to suit different conditions. I made a modification gallery with some pics: https://www.v11lemans.com/forums/index.php?app=gallery&album=268

    Marzocchi fork mod

    Pics of the method I used to fill the damping rod holes in the cartridge of a Marzocchi fork from a '99 V11.
  4. It's a '99 by VIN, build date 3/2000. The front axle has a nut, and does not thread into the fork leg.
  5. Awesome info, everyone! Thanks for all the links. Good to know my intuition was on point. My customer lent his bike to a friend who claimed it suddenly lost damping, but it seems it was always like that. I'll confer once again with the bike owner to clarify his goal (eg. more damping altogether, more progressive damping, etc) to make a plan around hole location/size and fork oil weight. I'll post the results when I have them.
  6. Hey, everyone! I'm a tech doing a light track day build on a customer's '99 V11 Sport. He complained of no compression damping in the front. I dismantled the left fork, and found nothing excessively worn or broken. I did notice, however, that the cylinder of the cartridge is drilled three times. This allows all the oil to puke out the sides, eliminating most of the damping until the ring passes the last hole, about 3/4 of the way through the entire stroke. This corresponds to the reaction I get from the fork leg compressing it manually, off-bike. Everything I've found indicates that this is the stock setup, and that it hasn't been mangled by someone in a past life. Now, Has anyone plugged or filled any or all of these holes in order to increase overall damping, directing more or all of the oil through the adjustable valve, thereby increasing the range of adjustability? I'd definitely be running 5w if I ended up modding it in this fashion.
