Suspension Setup recommendations.

I would try the .40kg . Raise fork oil level to 110mm from top. 5wt. You should bottom lightly on the biggest hits. If too much go in a click or two. 40-44mm static sag is good. Rider sag 75mm +-2mm. You are close. But personally I like even closer. Just turns better and is plusher.

Too bad we don't have a spring swap going. I've got .45's in my 50 zokes and could use something lighter.

I've used Vinduro's #s to get my 300 the nicest stock bike I've ridden. I'm 215 w/o gear and have a 6.4 on rear & the stock in front(42's?? still have to have them tested) A RaceTech Husky dealer told me to use the heavier springs that came with the bike, 4??, but I couldn't get the dang thing to turn!@#$, go figure. Still not perfect but getting closer every time I make a change. Thanks Dwight.........

Ok, I went with the .40's. With gear on they brought me too-

70mm rider
44.5mm static.

Seems that didn't make as big of a difference as I thought it would. Is 70mm good or would you recommend even lighter? I think .38 is the next lighter if they even let me trade again. I think I'm going to try an make a very small spacer to bring the preload just a bit closer. If I did, would that reduce rider sag?

Try the .38kg. The spacer will decrease your rider sag even more. If you have say 44mm static sag and 78mm rider sag you can put in a 5mm spacer to bring both into spec.

I don't know about twin chamber forks. Never dealt with them. Not as good for offroad from what I have seen. Much more difficult to service too. Not saying that they can't be setup decently for offroad but I don't see the advantage.

Sorry to keep bothering you.

I finally got a ride in with the new .40kg. Thought id do that and see how it feels before i return them so I have reference points. I also rechecked sag since the first time it hadn't left the garage. This time I made sure I had every peice of gear on I would in an enduro, including a full camelback.

Static sag settled in at 40mm
Rider sag settled in at 71.5mm

I rechecked several times and this is the average that they came to. Also changing the springs I noticed somehow I didn't have the oil level right I believe from settling in the forks and riding action getting a bit more air out. Im now "down to" 100mm.

Overall they feel great. Ive noticed I can corner sharper with the front tire not pushing at all and am draging my foot pegs into mother earth while confidently sticking to berms.

Would you still recommend going to the .38's? The .40's feel good and Im so close. Thanks again for your time.

You are right on the cusp. Now that you have ridden with the springs, I doubt the shop with exchange "USED" springs. If you could take out a mm or two of preload spacer you would be probably dead on. If you could get say 42mm of static , I bet you would have close to 75mm rider sag. Now have you got the correct rear shock sag ? Especially rider sag as that can effect your fork rider sag. Also I believe you need 110 to 120mm oil level which is lower than the 100mm you have currently have. Especially if you keep the heavier springs.

My rear shock is-

35mm static.
111mm rider.

A twist or 2 on the ring should put that right on the money. It should be 32/105. Would that increase my needed fork rider sag by just a bit then?

I cannot reduce fork preload at all. Right now as it is their is very little.

I bet if you add that "twist or 2 on the ring" you'll be right on for rear sag. Do that, and drop the fork oil level to 120-130 mm and see how she comes out. I bet you'll be right on the money with the 40's. And, those .40's are new... still likely to settle a mm or two.

Right on! I added a few spins on the ring til my rear static dropped to 30mm / rider 104ish mm.(which is closer to what they should be) I then rechecked my forks and they were 42/73. That seems perfect to me! I've got a weekend of riding coming up this weekend and I think I'll try the current 100mm oil level so I can know what it feels like, then I'll drop it a bit just before the following weekend which is our district opener enduro.

Yup, I too wish we had a spring swap going on. Everybody that has changed them has them laying around. I think I'd go back and respring my 08 with Zokes.

So following Vinduro's ideas, I pulled the racetech recommended .50s out of my forks and put the stock .45s back in. The sag numbers turned out about right, as far as I can tell. The rear 6.0 spring (also racetech recommended) gave the right sag numbers, so I left it in. It's been a while since I rode the bike with the .50s, but it does seem to ride better. If nothing else, the springs actually have a reasonable amount of preload on them, they're not close to rattling around.

Question: How are you all measuring the front sag so accurately? With the sticktion in my forks, I only trust my measurements to +/- a quarter inch or so. I've already made sure the forks are lined up in the triples correctly, and I think the front axle spacing is right. It still takes a fair bit of bouncing to get the forks to move. Am I missing something? The forks don't feel unusually harsh when I'm riding.

Oil the tubes for the measurement, but yes, you are right, a few mm's here or there are very difficult on forks.

I have a new to me 09 WR125 with the Zoke TC 50s and my sag numbers tell me I need new springs for my 175lb nekid weight..
My forks have .46 springs and they give me 34mm static and 63mm rider sag. After reading other posts here I'm tempted to order some 40 springs.
With a 5.4 shock spring, I adjust the preload for 32mm static sag and the resulting rider sag becomes 107mm. So to get down to 100mm. I need a heavier spring, maybe a 6.0?
I don't have access to a spring exchange, so I'd like try to get it right the first time..
Vinduro's weight is close to mine and the .40 and 6.0 were his spring choices for his 11 with the Showa/Sachs on his 11 if I'm not mistaken.

Is there a post around here for spring change on the TC Zokes? I heard there was, but can't find it.

I've got some .44 for the twin chambered zokes if you want to try em.
And I also have some .48's.

If anyone is interested in trading either of these for some .46's then PM me.


I also have a 5.2 shock spring I'd like to trade for a 5.4.


Now we've got a spring swap thread

Ok, thanks.

Well whatever the measurements are, the lighter springs really are working well.

Make sure to check at least 3 times and average your results.

Vinduro, it sounds like you settled on .40 and 6.0 for your springs? I am about your weight and plan to try that combo.for an 09 WR 125, w/CC forks. Do you happen to remember how much preload you used in the front? I have read and reread and can't seem to find it.
Thanks
