2019 Sachs CC Forks

[mcrag]

So I just picked up slightly used 2019 390 RR Race Edition. Looking through the manual, under Adjusting the Spring Preload it states "spring preload is adjusted by using the ring-nut". And it shows a picture of it - on the right side fork, just under the damper rebound clicker. My bike does not match this. There is nothing there but the damping clicker (it looks exactly like the left side fork). Anyone know why the discrepancy? And, more importantly, how to adjust fork preload? Thanks.

I don't think you'll find a preload adjuster on the left-just the right if it's like my 300rr. There's a sachs CC manual somewhere on the Sach website site now but right off the bat my left fork is looking different from the diagrams.

I would talk to Steve at afterhourscycle.com

Sorry, first time to the board in a while. The closed cartridge forks have internal preload adjustment capability. With the cartridge out of the fork assembly, slide the upper spring seat down (it will likely fall down, unless the oil keeps it in place). There is a circlip in one of five (or three, depending on the year) grooves. Move the circlip down to increase preload with a given spring, or up to reduce preload. There is one on each fork cartridge.
