das ist aber nicht das dropkit. das ist nur eine kappe.

LOW SPEED COMPRESSION – Even if you know all the above this may be something new. As I explained earlier the standard compression adjuster seems to have very little effect. The reason for this is that the compression cartridge has a series of 5 holes drilled (2 larger parallel holes at 4”, 2 smaller parallel holes at 4.75”, and 1 small hole at 5.25”) in it starting at about 4” into the fork travel.
Essentially, as the compression piston moves through the first 4” of travel, the oil in the cartridge flows out the drilled holes, allowing for a super plush first 4” to 5” of travel. As the compression piston passes each set of holes less of the oil escapes and more is pushed through the damping system, providing a very bottomless damping system at the end of its travel.
Running the fork in stock form I found that in most cases it was awesome and felt bottomless. However, at race speed I did notice that on very hard high speed hits the fork would reach then end of its travel suddenly. It would not bottom with a harsh noise or feel, but would allow my front wheel to deflect off large rocks. My personal preference is for a bit more damping throughout the entire range of travel, so I began looking for a way to get more progression from my fork.
First, I tried using the stock compression adjuster but noticed little if any difference. I tried up to 10 or 12 clicks, but noticed no difference. Second, I checked the oil level and found that I was running the maximum recommended. Third I tried swapping one firm spring for one x-firm. This was getting close to the feel I wanted and eliminated the defection, but I could not get more than 180mm of travel. In an attempt to get full travel with the stiffer spring I dropped the oil height a full 30 mm, but still could not get more than 180 mm of travel. Just when I was about to give up I heard about a new Low Speed compression adjuster than could be added to the 888.
I called Marzocchi and ordered the new part (about $50 retail), and prepped my fork for more testing by swapping the springs back to the stock firms and returning the oil height to the recommended 185 mm. When the part arrived I was pretty impressed with the machine work and could understand the cost. Essentially it is a sleeve that slides over the damping cartridge and can be adjusted to cover up 1, 3, or all 5 of the holes in the cartridge.
My first setting was covering all 5 holes. I found that in the parking lot I could get close to full travel (180 mm), but on the trail the compression kicked in so much harder I could not get anymore than 180 mm. On my second attempt I moved the LS damper to leave only the 2 larger holes open. This seems to be the ticket for me. I can get full travel (200 mm) on really hard hits, but it is much more progressive and no longer deflects on the hard high speed hits. An additional benefit is that the fork dives less when braking and on steep terrain, giving the rider a more balanced feel. This helps a lot in scary situations and when entering corners just after a hard braking section.
