Looks firm for a light bike

MXA did a review on the bike and pretty much said the same thing.  I can't comment though as I really didn't ride the bike before I opened the forks to see what was in side.

You going to stick a 07 yz 125 stack in ?

Well, that wouldn't be surprising considering their company size and resources.

 

 

 

Per the valving I do like the stock yz125 valving.  I wanted to try something a little bit different for 50/50 woods and sand though.  I tried the valving below on a mostly sand trail and the forks worked well.  I need to ride it on an actual woods trail though.  I will try to get to the shock this week.  It had obvious issues in sections where there were roots.

Shock valving below. This does have the check valve like most of the other Sachs. It also uses 16mm ID shims which of course I have none of.

Not sure where I'm going to start with this yet. I think I was running something like 16 out on lc / 11 out on hc and 11 out on reb when I road last time. It wanted to swap in sand whoops and was popping up a bit if I tried to get on it in root sections.

Finally got to test the stacks tonight on a real trail. Lots of loose rocks up to grapefruit size, roots and stumps. The fork actually worked really well. I was rather surprised to be honest. In the sand I ran 10c/9r and on the trail I ended up at 18c/9r. It tracked quite well in the loose rocks, held it's line well in all corners and was rather plush in even the big roots.

The shock on the other hand didn't work quite as well. I started with 15lsc/12hsc/12r and right off the bat the rear was swapping in whoops and a bit all over the place in rock gardens. It also wasn't nearly as plush as the front I eventually got the rebound down to 8 clicks out before I stopped there. It stopped most of the swapping and helped with the control in the rough. I didn't want to go in any more as I knew it needed attention. I noticed that the rear got plusher in the rocks the more I went out on the hsc. I basically ended up 2 clicks from full open for that. The lsc was best around 14-18 clicks out for balancing control vs plushness.

I know this shock uses a slightly heavier weight oil but I only had Maxima 3wt shock oil on hand. I noticed when I got the bike back together that the free bleed just pushing on the rear seemed noticeably faster than the same setting stock. The shock felt nice and smooth after the rebuild so I ran it anyway. I guess I may need to try a heavier weight oil before I do much else with the rebound.

I ran:

Tested a new stack for the shock today and it works drastically better. Decided to try a rebound stack similar to one in a thread over at Cafe Husky. Wasn't really sure how it would work out but the bike really works well now in roots and rocks. Also switched to some 5wt shock fluid instead of the 3wt. Not sure if that helped or not.

Shock compression looks stiff (for rocky/rooty trail use). Try a 20 mm clamp and possibly removing a face shim.

Looks like you went quite a bit stiffer on rebound, that isn't the direction I went with mine but it's up to you. I am pretty close to stock on rebound on mine.

I found that the rear of my 300 was popping up coming off singletrack whoops and logs, so I thought I needed more rebound, but it actually was too much compression causing deflection. Less compression and going back down on the rebound helped that problem and regained some traction.

Thanks for the suggestions.

 

 

For the rebound, restackor is telling me my current stack has a fair amount less lsr in the 0-20in/sec range.  From there it's stiffer through the rest of the range.  I think I'll try you're suggestion with the comp stack and go to a 20 on the clamp.  First though, I still need to ride the new stack on some sand trails.  It's always a bit difficult for me to find the compromise between performance on rocky/rooty trails and trails that are just straight sand.

FYI the series I race has about half its events in sandy conditions. I don't know how fast you are but I'm B/C level and I never bottom my WR300 in the rear on whoops or g-outs and I am running an 18 mm clamp (!!). It would be soft for moto, but for the smaller jumps we occasionally have in hare scrambles it's fine.

To start, I'd go to a 20 mm clamp and possibly swap a couple of the shims in the taper for thinner shims.

Let me know how it works out!

Got to ride the bike on a real sand trail today.  It's an orv trail that's mostly composed of deep sugary sand that bikes will just sink in.  

 

My woods settings were:

 

Fork:

20Comp

11Reb

 

Shock:

24Lsc

27Hsc

8Reb

 

 

Obviously that didn't work well but I had to go quite a bit stiffer on everything to get some confidence with the bike.  I'm not sure if I can go any lighter on the comp stack with the shock.  Here is what I ended up with for the deep sand.  Need another ride to fine tune further but this worked pretty well.

Eh, I went ahead and ordered some of the shims for the shock anyway.  I had to order some other shims so I just tacked those on.  I think I may be able to swap out some of the smaller hs shims like you suggested.  Should be able to reduce it little bit more without it effecting the ride in the sand to much.

It's definitely hard to have a setup that works really well in woods and sand. I change my clickers quite a bit (like you did) going from slow rocky stuff (1st gear embedded rock gardens) we ride in half our series to fast sand (3rd gear whooped singletrack), and it's still sort of a compromise.

Update for the shock.

 

First I found part of my problem was that my sag was in the mid 90s.  I had my wife help me and that didn't work out so well it seems.  I adjusted it to 100-102mm and did a full session of tests.  Shock has roughly 38 clicks of rebound, 29 clicks of lsc and 20 clicks of hsc for adjustment.

 

I tried something a little bit different.  On the sandy trail I started with everything way out and moved in stiffer/slower until I couldn't perceive an improvement in ride quality.  For the sandy trail with rocks I ended up at 17hsc, 18lsc and 8reb.  I did the reverse on the hard pack trail where I started stiffer/slower then moved faster/softer until I couldn't perceive a benefit.  For the harder pack rock/root trail I ended up at 20hsc, 24lsc and 9reb.

 

Rebound in whoops for both sand and hardpack was holding me back from going further out. It was just too springy off each whoops.  Deep hardpack whoops were worse than the sand whoops.  As far as I know whoops are more lsr which makes me think I went a little too far at reducing it.

 

The hsc had the most notable changes on hardpack.  The further out I went the better the ride height was in corners but the worse it felt going fast over loose rocks and roots.  The ride height change couldn't really compete with a plusher ride at speed so full soft was the best.

 

Looks like I need a bit more lsr and need to reduce compression overall.

 

 

The forks still work awesome especially with the sag fixed..duh.  You can absolutely tell the difference in a few clicks through the rough stuff.  18c/9r just eats up rocks and roots without any deflection while giving enough room to go firm in sand.
