05-06 Marzocci valve specs

[pobit]

I happen to have two sets of forks appart today. An 05 DE200 and a 06 DE300. I found the Base valving is quite differant between the two years. The valves themselves are differant also as the 05 uses a 1mm bleed hole in the side of the port and the 06 uses a 2mm hole. Other notable differances is the 06 uses a bleed shim on the face with a 22mm shim that covers the ports. The 05 does not use a bleed shim but uses a smaller 21mm shim that does not cover the ports completely allowing some bleed. The cartridge, damper rod, bottoming cone and rebound valving is the same on both years. Only the base valves differ. Here are some pictures showing the differant shim stacks and differant size bleed hole in the base valves. Anyone have any imput on why the changes? Dave

I heard about them using the bleed shim. If you thought it was soft I guess you know why now. I assume that bleed hole in the base valve is the path for the comp adjuster?

I wonder if the Husky Zokes use the same base valve? I know they don't use a bleed shim. Even the heavier TE450 stays up in the travel nice without being harsh in the rocks.

What does the rebound/midvalve (checkplate?) look like?

The bleed hole is in the port that the oil flows through the shims. It appears to be a by pass for one port. The mid valve is a check plate . Dave

Wonder why the obsession with so much bleed?

Do you like the fork better than a WP, especially on the sharp edge (HSD) stuff?

Have any of you guys revalved your own 05 or 06 forks? What shims stacks did you use. There doesn't seem to be a lot of info on these forks anywhere so we might as well start a thread here. The first thing I am going to try is removing the 11 bleed shim on the face of the valve to see if this helps get rid of the mushy lack of feel these forks have. I don't know if this will make much differance with that big 2mm hole in the 06 port. Has anyone tried plugging the hole? Thanks, Dave

Pull the bleed shim and first crossover.

This is what l used on my 05 forks. 4 22x12, 14x10, 20x10, 18x10, 16x10, 14x10, 12x10 and 25x11

Is this bushing land issue unique to GasGas Zokes, or Huskys also? I ask because the Huskys I've ridden with LTR valving exibited NO bad habits. If anything, the overall bushing/tube fit seemed more relaxed, giving the fork very little stiction. I've had Husky Zokes apart but not that bushing, and didn't notice the fit.

I mentioned this to Les @ LTR - he revalves several sets of zokes a week, both husky and gasgas...

• He said he has never seen a clearance issue with this bushing; As a sidenote - He has seen wear associated with overtorqueing the triple clamp bolts, etc. (like any fork).
• He has seen four different compression pistons used over the last couple of years with varying amounts of bleed.
• What appears to look like a checkplate and spring can actually act as a mid-valve - depends on the tension of the spring.

Today I measured the thickness of the shims between the 05 and 06 and found they are differant also.

06 stk 05 stack
11x20
22x10 21x10 the 21mm face shim does not completely cover the ports on the 05 so there is some bleed.
11x20 11x10
19x10 19x10
17x10 17x10
11x10 11x10
16x10 16x15
16x10
15x15 15x15
14x15 14x20
14x15
13x20 13x20
12x20



Notice the 1st cross over is a thicker 11x20 in the 06 stack and the doubling up of the thinner 16x10 and 14x10 with the smaller 12x20 pivot. Keep in mind the 06 valve uses a 2mm bleed in one of the ports compared to a 1mm bleed in the 05. Anyone care to comment on what GasGas was thinking with the new specs? Dave
