YZ sag question

[Yamadog]

Does anyone have any recomendations for me on the best sag messurement for my 1991 yz250. I have set it at 95mm. and it seems pretty good but it does kick a bit, although I have heard this is a trait of that era yz suspension. Anyway should I go to 100mm or 105mm? Any imput on what this era yz seems to be most happily balanced at would be grate. Also I'm not sure it matters but I am 6' and 175lbs. Thanks.

i think i would try to tune the shock a little before i messed with the sag anymore. sometimes a little softer or stiffer can do the trick. on my quad(no clue what the sag is) i have had to soften it up just a little. mine used to kick up bad till then. but a bike and quad are two of the biggesat different things to compare to each other LOL someone wil surely be able to help out here. good luck and be carefull

Assuming it has the stock shock spring on it, set the sag at 100mm, set all the clickers to the stock postions (turn them all the way in and then turn them out 12 clicks) and go from there. 95mm is not enough sag.

Thanks satch0922. I will try that and don't worry I even have a sag mesureing tool to help out with the process. Plus one of my more recent mags has a great in depth article on the correct way to set it up. Although I thought it said 95mm was enough. Though I think that was a minimum and it was some what generic or not old yz specific.

Wouldn't sag still be set the same regardless of the spring type. I mean you want to set a bike for the correct sag regardless of what your perticular sring rate you have to match your weight. Right?

talk to VET he always does that stuff to my bike he will know

sometimes with an aftermarket suspension, springs and shocks may have a different setting. say a stock spring will be a 100lbs, but if ya buy one from an aftermarket company, their 100lb spring may not be a true 100. it may be off a little. so unless you can calibrate them at home, you need to measure. shocks are the same thing, there all different in one way even if they say their the same. does that help any? its confussing thats for sure. of course i could be wrong to.

the reason I said that is because uyes....youc an set the sag with any spring...but it will be so far up or down in the spring's "stroke" that it will either be harsh (because the spring is compressed too much to acheive the proper sag) or it will be too soft in the initial stroke because the spring is too stiff and not enough preload to achieve the proper sag.

Hope that makes sense. Bottom line....make sure you have the correct spring rate and then set the sag. 100mm trust me...this will ensure the bike handles like it should.

Do what Satch says then I would try 105mm and go back to 100mm then 95mm. See what works best for you, your riding style and the terrain you frequent.
Satch knows of what he talks with the YZ but he is a motocrosser (not a bad thing) but if your a trail rider it could be different for you and the trails you ride. The one thing you want to do is look at what terrain you ride, tracks, trails, desert then go to that terrain get a nice trail with a lot of varying terrain and play with it.

100mm should do the trick but it is a personal comfort that will tell you what is truely correct. Cornering will change with each setting, pay attention to that when you are testing each setting. Once you get the best sag setting for you and your bike play with the clickers (compression & rebound) for the plushness you desire in your ride. 95mm to 105mm sag is the general range you want to stay in. If your heavier than your suspension is set up for it may stray out of that range until you get the correct springs and valving done to match your weight and riding style.

There are many articles on setting the suspension clickers and sag. Read if any of it is confusing. Ask questions here and Shocknut or many of the other knowlegable guys and girls like Satch will answer.

Good luck hope all the answers help and lastly post your results so we all can know what worked for you the best.

SATCH when you say turn the "clickers" all the way in then back out 12...which way is all the way in? i assume you mean creating a 100% tight spring? but then mines an 04' so it may be different on how many to turn back out

[Dirtbikindad393]

Clickers:

In = Clockwise

Out = Counterclock wise

Not to be confused with the spanner nuts on the rear shock that would be turned while setting sag. That would be clockwise to tighten or compress spring more.

DBD...both of those points are debatable! LOL

Thanks for clearing up the "clicker" confusion.
