Customer sent a ragged out Ohlins off a much used 2006 GasGas. The shock itself wasn't so bad. Whoever worked on it last was somewhat the hack and it lost its gas. It was also run rod side up and the seal head area was pretty packed with dirt. The fix was some machining, cleaning, and fresh oil. The seal head was still good. I pressed in a custom Schrader valve because the hat had been welded on one side and screwed up on the other, so I just plugged it there. Ended up revalving and modifying for longer travel while in there. Why not? It's SO easy to do so, and it gets rid of the short-harsh feeling typical to these shocks. The former 12-year-old junk should now out perform the latest shocks. We shall see, as I got creative on the revalve. Interesting to find the shim specs the same as the later GG4512. Also, I found a very wide range of bypass adjustment. Very fast on the return at zero clicks. Glue slow at 34 clicks. Nice! Ohlins is #1 in ease of maintenance and modification! Glad I have Ohlins and not Reigers on my Shercos. FYI I have an error in the photo above, which shows stock valving. There are actually two small rocker shims in the compression and rebound stacks. They were just stuck together so they looked like one in each place.
