Query - standard number of exposed threads on base of shock

Oops - I've stuffed it up. I forgot to count the exposed threads above the shock clevis. I lowered the bike and found the chain slipper getting munched badly, so wound the clevis down again. Trouble is, I've gone too far, I think.

Anyone know the standard setting?

I would like to know as well.

Make sure the rear suspension is fully extended, take a measurement from the axle/swingarm up to some point on the frame above it with a measuring tape, then go to the dealer or to another known stock bike and make the same measurement  

Set the sag correctly, you cant use the number of threads to setup your bike.

I think everbody wants to know the stock rear shock height. Im not 100% sure but I think its 26" from center on axle to helmet lock

I know, im with you so far, I just fail to see to what point, unless you somehow know that at stock settings, it would be correct for your weight/gear and ridingstyle ect..

Static Ride Height and Sag are two different things, once the static height is known, then you can move onto sag and preload.

Anyone have an answer on this? I'm in the process of rebuilding the shock and the shaft rotated, or screwed into the clevis, while removing the top nut. I'd like to know approximately how far the shaft is in the clevis, in a non lowered shock. Jens, I think you misunderstood the question, btw. Any help would be appreciated.
Cheers,
Brent

Are you asking about this area?



To the best of my knowledge, this adjustment is as Yamaha shipped it.
I am not original owner, but I never changed it and I bought the bike with only 300 miles on it.

Sorry for the blurry pic, but it's about 4 or 5 exposed threads. If that is indeed what you're looking for.

Motokid,
Yes! That is exactly what I was looking for. I really appreciate you taking the time to not only answer but show an actual picture. Thank you, not only for answering this question but for all your input on this forum.
Cheers,

Yes, thank you for all your replies. Thing is, I'm sure that the original setting is more that 4 threads, since I screwed mine down to about that from stock.

Back to the drawing board... I'm going to my dealer next week, so will count the threads on a display bike if he has one, and post the result.

Another way to possibly "check it" is seat height.

A wr250r seat height is 36.6 inches
A wr250x seat height is 35.2 inches

not sure if you still find this helpful, but I count 7 threads on mine. Bought the bike brand new, never messed with the suspension.



While we are at it, (maybe someone else in the future will stumble upon this and be thankful for it), the threads for the stock preload:



and excuse for my dirty bike, haven't started with winter cleaning yet


ps: according to the manual the spring in "standard" position should be 211.5 mm long

Thanks for posting, bigg. I'm sure it will help someone out in the future.

I visited the Yamaha dealer yesterday. Unlike the photo above, there is an unthreaded area under the rebound adjuster.

Anyway, there were 7 threads visible, much like bigg's pic.

Looks like 7 is the magic number. Thanks to all

As an FYI...

The adjustment at the bottom of the shock is a nice little way to change the geometry of the bike.

If you want a little quicker handling bike you can have more exposed threads - it raises the back of the bike.

If the bike is too nervous for your liking then reduce the number of threads showing - drops the back of the bike.

Of course before you do all this make sure your pre-load is setup right.

This was the method in my madness in the first place. I have a very tall Pirelli MT43 on the back, so attempted to compensate for it.

Thing is that the front slipper really started to wear unacceptably, so back it went to (almost!) stock.

Frankly, my WR doesn't really care about any adjustment. It goes about its business unaffected, so it seems. Odd.
