Stock shim stacks for the Marzocchi Shiver 48 on 4Ts
Posted: Sun Dec 22, 2013 11:45 pm
Hi!
Recently I changed my RR250 to an RR400 Factory 2012 with the red Marzocchi 48mm fork. I just had a long ride in the woods and the forks were really harsh everywhere, moving fast up and down using much of the travel and then stopping suddenly about 7-9 centimeters from bottoming out. I checked the compression shim stack yesterday and I found the following:
32 - 0.1mm (x10)
20 - 0.1mm (crossover)
32 - 0.15mm
30 - 0.1mm
29 - 0.15mm
28 - 0.15mm
26 - 0.15mm
24 - 0.15mm
21 - 0.15mm
20 - 0.15mm
18 - 0.15mm
16 - 0.15mm
14 - 0.15mm
12 - 0.15mm
11 - 0.2mm
I think for those who have tried even once to revalve their forks it is obvious from the description above which parts of the shim stack cause the harsh behavior (blowing through the stroke until there is lots of damping later from the 2nd stage). Also in the external chamber there were only 270ml of oil and the PFP was stuck full open (10 turns out).
I am going to try the following with 300ml of oil in the outer chamber and 2 turns in for the PFP:
32 - 0.1 (x6)
30 - 0.1
28 - 0.15
26 - 0.15
24 - 0.15
21 - 0.15
18 - 0.1
16 - 0.15
14 - 0.15
11 - 0.2
It would be a bit different and without the thicker 0.15mm shims but currently I do not have enough spare shims.
I would be really thankful if somebody could provide the stock shim stack for the Beta 4Ts.
