Hi Jazz62.
When i fitted a trail reducer to our bike after fitting a sidecar the front was to low so i was told to put a few washers or a spacer on top of the front shock (That is on top of the shock before you fit it to the bike ) I think i went with a 10mm or 8mm spacer .
It did make a differance to the ride hight .
I did have to lower the bike down to put some weight on it before putting the top nut and washer on the shock .

If your rear is to short i do not know if you will be able to do to fix that .I am not sure if you can just tunr the top eye out to make it longer ?

Cheers Ian

Thanks for the ideas Ian. Nothing's been easy with this bike so far - for grins, this thread for instance:

http://advrider.com/forums/showthread.php?t=779880

but I know the satisfaction of having everything "right" will be worth the effort and I'm learning a lot along the way.

Edit: Just removed the front shock and it is just about 10mm shorter than the stock unit.

If it is stiffer the length might not be that important.

(sorry if that didn't come out as it was supposed to)

My wilbers arrived from service today.
I'll check the length against the original.

Thank you, I'm very curious to see the difference if any. I read that the standard length of a front shock should be 337 mm from center bottom eye to top of the washer. The rear shock should be around 383 – 384 mm from center to center for a standard length shock.

I haven't removed the rear yet but I read that the ratio for the rear is 1:3, meaning if the rear is 10mm shorter than stock then the ride height difference is - 30mm. I don't have any illusions about doing any serious off-road riding but 30mm less ground clearance is not what I want from this bike even on the road.

Had a lot of people here this afternoon for (dry/gin) martinis; sort of lost focus.
Tomorrow - I promise.

On top of the shock there is a washer, then a spacer (holding two rubber things) and finally on top another washer.
From the center of the hole to the top of the first washer it is 336 mm.

But it seems that this could be adjusted by turning the two big "nuts" that hold the spring; probably need a special tool for that.

This is the second time I have mine serviced. Paid 220 euro included shipping both ways.

Gracias Senor Tagesk!

My front Wilbers front is 316mm.
OEM front is 326mm

I believe that turning the big adjusting rings only changes the preload but I don't think it alters the shock length.
Tomorrow I hope to remove the rear and take a measurement.

I was told that the ratio of shock length difference to ride height for the front shock is 1:1.4
Your front Wilbers is 20mm longer than mine.
20 x 1.4 = 28mm
28mm = 1.10"

It's probably safe to assume that my Wilbers are lowered by 1 inch, tomorrow's measurement of the rear will confirm.

Well again, more troubles.
Trying to remove the rear shock to measure it.
The lower shock bolt came out considerably, bolt head completely clear of it's recessed hole, then stopped coming out. Just turning in place. I did the original swap without having to remove the exhaust as it was easy to grab the bolt head with some pliers and I was doing it the same way this time. I've tried pulling on the bolt head, the swingarm is supported so it's weight is not causing the problem hanging up the bolt. I did notice that the eye/spacer of the shock is also turning but I think it's supposed to, right? It's not threaded as far as I know. I've run out of ideas and I did something bad to my back, it's fucking killing me.

Any help out here greatly appreciated. Can't work on her at the moment, threw my back out something terrible.
Still trying to figure out why the lower rear shock bolt won't come out all the way. It's come out far enough that the bolt head is completely out of it's recessed hole with even about 3mm of gap behind it but it won't come out any further. Thanks in advance.

My WIlbers are here on the table in front of me.
As soon as the rain stops (rain in Tuscany ) I'll remove the rear and look at that bolt.
In particular, I'll find out if all the threads are free when there is a 3mm gap after the head.

Or, in other words, if you "just" need access with a bigger pair of pliers to simply pull it out with force.

Thank you Tagesk. Would you be so kind as to measure your Wilbers rear eye to eye for me before you install it?

On mine, the lower bolt on the front is the same as upper and lower on the rear.

The length of the "bushing" (the thing the bolt goes through) is not the same.
You want me to measure the lengths of these?

No, just the length (height) of the rear Wilbers shock from bottom eye to top eye. Like you measured the front.
