Beta 350rr 2016 shock std stacks

Posted up in a few places I know a few of you here have some interest. Can see some areas that need improvement.

Sachs

Comp
44x0.15 (2)
44x0.2 (5)
40x0.15
38x0.25
32x0.15
44x0.15
42x0.15
38x0.2
36x0.2
34x0.2
32x0.2
30x0.25
28x0.25
26x0.25
24x0.25
22x0.3

Reb
38x0.2 (4)
36x0.2
28x0.1
36x0.25
34x0.25
32x0.25
30x0.25
28x0.25
26x0.25
24x0.3
22x0.3
20x0.3

Really happy with this shock very well made. Pulled it apart to service it at 60 odd hours and the oil was like new. Little bit of a shim shuffle too

Here are my ideas
This area here is an issue.
40x0.15
38x0.25
32x0.15
44x0.15
Its a big gap to the 44. Was thinking of removing the 40x0.15, 38x0.25, adding one 44x0.15 and leave the crossover as is.

The idea in my head is for the highspeed to come on earlier as the gap is smaller and the added face shim gives a little more stiffness as removing the other two will soften the stack. Ideas anyone had experience with these.

Cheers
MM

be interesting to see what works best marty. when FFRC put the shock from my RR300 2016 on their dyno they said it was one of the best stock shocks they'd seen.... they still managed to improve on it a little though. the forks won't so good though, they managed to get those feeling quite a bit more plush.

Have to agree the shock is pretty close just a bit of a wallow have used it for 60hrs Raced on the weekend and decided it was time, funny how you lift to another level when racing.

The forks are better on the 4st even through they are similar in valving to the 2st just too soft they blow through the stroke, pretty happy with mine atm. Who did yours or did you do it yourself ??

The new stack and the ideas behind it.
Comp
44x0.15 (4)
26x0.15
44x0.2 (5)
removed 40x0.15
removed 38x0.25
removed 32x0.15
shifted to the face44x0.15
42x0.15
38x0.2
36x0.2
34x0.2
32x0.2
30x0.25
28x0.25
26x0.25
24x0.25
22x0.3
I think one of the issues was the 40,38,32 shims after the face its a huge gap for the 44's to cross to the high speed which is why its vague and wallows a bit. The small crossover was an idea from a good tuner who only goes up 2mm from the clamp for offroad so really is a trial for me I only had 26. I added the two 44's to the face as removing the other shims took a fair bit out of the low speed part of the stack. Its an educated guess at this stage will report back how it feels. Any one else played with a later Sachs shock care to offer some words of wisdom??

You stack looks significantly softer to me, across the board.. I don't think it'll offer support and will wallow quite a bit more than it does already. What were you hoping to achieve in particular?

I agree with the other tuner, that if you wanted to go a bit firmer I would simply clamp on a 23 or 24mm shim instead. If you wanted to get rid of the big crossover gap you could do something along these lines.

44 x 0.2 (5)
36 x 0.15
44 x 0.15 (4)
42 x 0.15
38 x 0.2
36 x 0.2
34 x 0.2
32 x 0.2
30 x 0.25
28 x 0.25
28 x 0.25
24 x 0.25
22 x 0.3

..again if you wanted firmer than where it is now I'd either add a few more shims into the stack (replace a couple 44x.15's to .2's) or clamp on a larger OD. I'd possibly even be inclined to drop a couple more face shims onto the stack.

I see some remove for improvement in the rebound stack potentially. Where are you running your clicker at the moment?

Also, you know of anyone with the stacks for the 250/300RR model? Haven't been able to find them. Have done some work on the husky 2T's and Gassers which both run the Sachs shocks. Few variations in terms of top out setup, and also 16mm and 18mm shaft varieties to be aware of.

i couldn't even pull a fork apart marty, complete mechanical gumby here lol. got full force racing components to do the full suspension makeover. from memory they didn't adjust the valving on the shock at all but just made their own custom shaft, they said the differently tapered needle would provide a bit more adjustment. no details on the shim stacks for the front, i could ask but i suspect like most tuners they won't hand out their details....

i'll get the new RR480 up to them sooner or later. seems to be a similar situation to the old RR300... rear end is great and while the front is good in most situations it could just do with a bit more plushness. backed right off the compression damping but still a bit harsh riding fast through our rocky creekbed.

Idea was to get into the high speed with more progression than now! I think the gap was too big this made the bike kick around on braking bumps.I raced our first state enduro round here a few weeks back there was lots and lots of cap rock and off rocky cambered corners. The bike felt pretty good up til about 90% then the rear gets a little out of shape not tragic just room for a little improvement. I'd like it more plush over large square edged braking bumps. I didn't calculate out how many 0.15's the 0.25 was I should have but just worked with what I have, its all gassed up now so will try it this weekend.

Funny you should ask about the rebound. I run the clicker at 8 out in really deep sand and huge WA whoops. On the hardpack I run it at 10-12. 10 is a fraction slow 12 a bit to quick and 11 is ok not perfect but ok.

As far as stacks go I have very little on the Sachs shock read nothing There are a few threads on TT about them on Huskies but the stacks are crazy maybe the 18mm shaft I didn't know that. As for the forks I have a few stacks I could share if you like. Thanks for the input....

Cheers
Marty

Try winding comp up on the fork and see how it feels sounds counter intuitive but give it a go If you have a look at my fork revalve thread you will see the rebound circuit std is just silly backed up by feel and DBW79's feed back. I could not get it to work unless it was 6 clicks out and this effected the comp. Great bikes but like most they need a shuffle to get them right. Enjoy your 480 everyone I know who has ridden one loves it.
