The other night I was trying to dial in my suspension via settings suggested by the service manual. I noticed when I back the preload adjuster for the rear shock all the way out and then start turning in, the first few turns have zero resistance. It feels like the first three turns are doing absolutely nothing. After about the third turn I can feel some resistance in the knob like it's actually adding preload to the shock. Is this normal? If not how do I fix this? Since we are on the topic of suspension, is there any service or maintenance required to the rear shock? How about the forks? At what intervals are you guys changing the fork oil? And what fork oil are you using? Thanks for the help! | ||

The adjuster needs oil added. There is a thread somewhere here with details. | ||

I've done the front leg oil 15-20,k miles. tried couple times with the read shock preload oil refill. But my problem was that the nitrogen had leaked out. Hit rebuild and resprung by a race tech authouri,ed shock shop in state | ||

I have searched high and low and I can't seem to find a procedure for adding oil to the preload adjuster anywhere. Does anyone know where this can be found? | ||

Here’s the procedure: Back off the adjuster knob completely. It may be a good idea to support the rear of the bike so no weight is on the shock. Detach the adjuster from the bottom of the seat pan (2 bolts). If you have the fan shroud from the cooling kit installed, it gets in the way and has to be removed or bent out of the way to give slack in the hose. Disconnect the hose at the adjuster by removing the banjo bolt. Plug or tie up the hose so the oil doesn’t run out. Hold the adjuster so that the hose attachment hole is pointing straight up. Take a small tool (screwdriver, o-ring pick, wooden skewer, etc.), insert in the hole and push the piston all the way down. It’ll usually move 1/4” or so. Pour oil in through the hole until the adjuster is completely full. If significant oil leaked from the hose, it’s a good idea to refill it too. Carefully reconnect the hose and tighten the banjo bolt while spilling as little oil as possible. Re-bolt the adjuster to the bottom of the seat. After this, you should start feeling load on the adjuster after 1/2 to 1 turn. It can make a big difference. (Message edited by Hughlysses on June 12, 2018) | ||

Awesome, thanks much for the write-up Hugh! I will give this a shot this weekend. | ||

think I'll try it. What oil? will fork oil do the trick? does it matter if it is not the same as what is already in there? | ||
| Tleighbell |
whoops, missed the earlier answer. hydraulic jack oil? Is that the only option? | ||

Nearly any oil. Fork oil works well. |
