I'm selecting my shims. I want to make sure I get this right because it's such a pain in the butt to get into the forks this far. I'm 320#s and I ride in the tight woods. On the chart I'm coming up with LC5 for low speed and HC4 for high speed. Anyone else have this chart handy and can confirm this? I think you start on the left of the page and make your corrections from there? Am I doing this right? John is a good guy to deal with but his manuals really suck.

 

Instructions say for 20 lbs go right one with 180 as a base line. If you are 320? Go right 7 spaces. Instructions are at work, I will check them in an a couple of hours.

I don't ride dirt, so I will try to shut up.....

No, please don't shut up. It says the 180# base line on here. So where on the chart would a 180# guy start? If it's starts on the left, a 160# guy is up shyt creek.

 

Dumb-*** me. I shouldn't try to follow directions at 2:00AM. Now it's 7:00AM and I can read. The low speed starts at lc4 for a 180# rider and high speed starts at HC5 on the chart for a 180# rider. Never mind.

 

Its that helper you had in a bottle

Enjoy.


I set mine at HC10 and LC10.

Later, when I work on this again, I'll have more dumb questions. One of which I know I'll ask, is about #6 in the directions, describing the orientation of the different stuff on the compression bolt, which appears to describe it upside down from what I disassembled Last night. Then again, that might be me being dumb again.

So I put the 2 original base plate washers down, then the high speed shims on first in the order specified by the chart, then I put the low speed shims on top of that the same way, then the green valve disk, then the spring, "new" spring cup I didn't get, then the purple sleeve nut. I think we're good. I just need some blue locktite and my buddy's torque wrench.

 

FD, can you list the shims...diameter, thickness, and how many...instead of the MP designations of "lc4" and such? I'm curious about something, plus I want to see if our shim stacks are close to each other between the RT and MP kits. It would be interesting to know.

 

First on the stud are the spacers that keep the valve centered and the nut completly on the threads.

Next are the shims for High Speed Compression from smallest to biggest diameter going from the bottom of the list up.

Example:

FIRST on the stud for HC 10 or setting #10 of 20 choices

9mm OD X .1mm thick
11mm X .1
12mm X .1
13mm x .1
14mm x .1
17mm x .1
and TWO 17mm X .15mm

This completes the high speed compression valving

NEXT is the low speed compression I will use #10 as I did on my bike.

ONE 12mm X .10mm shim
TWO 17mm X .15mm shims
THREE 17mm X .10 mm shims

So I have a Club sandwich of shimms. It makes total sense to me.

Don't forget I listed them from bottom to top.


Then the green valve with the bigger holes facing the shim stack so they will seal

Next are two shims that make up the check valve. The hole in them is bigger to fit on the purple nut.

Next is the spring and the nut.

I used the supplied check valve because I thought it was pretty instead of the stock one. Besides it just looked like it would work better.

All those colored anodized parts that no one will see.

A few more examples.

LC4 is the stock suggested low speed compression stack which is one 11mm x .1 mm shim and three 17mm x .1 shimms. Not counting the first one that allows the shim to bend we have .3mm total thickness for low speed compression. Going up to our original setting of # 10 low speed, we have a total of .60mm of thickness. LC13 which is as stiff as the chart goes used four .15mm shims or still .60mm but in a different configuration.

make any sense at all?

Its up to thirty-something* f, still no riding Roads are wet and salty.

I'm done work!

OK, here's the RT compression stack.

Low speed compression--(2).15 X 17, (2).10 X 17, and (1).10 X 11

High speed compression--(1).15 X 17, (1) .10 X 15, (1).10 X 13, (1).10 X 12, (1).10 X 11, (1).10 X 10, (1).10 X 9

Interesting to see the comparison as there are some differences in the stacks for sure. I'm 185 pounds for comparison. RT also asked me if I had a larger capacity fuel tank, along with all the other factors of age, aggressiveness, terrain features, etc. My shim chart shows a total of 10 possible stacks ranging from soft to stiff if I want to alter the damping. My recommended stack that I'm running is just to the right of center in the stack chart. This stuff is interesting.

 

I need to get on this. sounds like a sweet science to me. Race Tech or Moto Pro? Hmmm..
