Probably Marzocchi 45mm open chamber forks. Measure the stanchion tube to be sure. What do you need to know?

Sounds like Sachs 48mm OC.
The bleed hole is some small allen head (like super small - 3mm maybe). From all I read I think the air gap is around 120-135mm fork compressed, spring out. I run mine at the full 135mm on a 2010 EC300 R. I'm pretty sure every year GG has used Sachs they've had different valving. Trying to source parts for these forks is more than a headache. I think they came with 2 sets of fork caps too! One wiith adjustable preload and one without. PS The Sachs have a strange rebound screw that can be competely removed from the cap. Don't strip the threads on it when re-asembling, and don't ask why I know not to. PPS. The parts from when I damaged mine months ago are only just shipping now. |

thanks jacobi i think your right .i have a problem with the 1 forks rebound adjuster it doesnt seem to work right i was getting no rebound at all.the rebound screw can be pushed out of the fork cap with the ballbearing/spring and grub screw in place.

Sounds like you must have the ones with the preload adjustment. My caps were very simple. Cap, bleeder hole, and the brass screw (which had an o ring on it). The rebound screw threads into the damper rod and I misaligned putting the cap on and cross threaded it.. oopps.
Hope you don't have the same problem. Compression clickers are at the base of the forks and require a quite large flat blade screw driver to make adjustments. |

When you wind the rebound screw in does it click and go in easily and eventually bottom out? Or is it just spinning on the spot. Once the cap is removed you should be able to push the reboudna djuster out completely, feed the thread back into the damper rod until it bottoms and then install the cap.

forks
ok i have cleaned and reassembled filled with 5 weight 125 airgap and they feel pretty plush.the fork took a bit of fiddling to get the same amount of clicks both sides 18 or 19 i think.the fork caps were the standard rebound only ones with the compression on the bottom of fork.i will be drilling and tapping the fork cap to take some speed bleeders to get rid of the stupid little screw.another thing i will have to look into is moving the handlebars forward so i can adjust rebound without removing the bars.now all i have to do is ride the bike and adjust comp and rebound on forks and the ohlins rear shock i fitted from a 450 vor a friend has broken for parts.

I ground some flats onto an old 4mm allen key, cut down so that it will fit under the bars. I carry that in a plastic tube taped to the clutch line, so I can stop and make adjustments out on the track.
