650 adjustable shock

[pdsquire]

If turning the adjustment screw doesn't seem to make any appreciable difference, is there something wrong?

Thank you, Richard!

sorry philip couldn't resist, Have you turned it right down then back to the middle to get the factory setting then go fo a harder setting,sometimes I think the valve gets a bit stuck in the same position as they rarely get adjusted.I only ever adjust mine if i have large amounts of luggage.

It does bugger all in my experience too!!

I had the rear shock really wound up last week going over to France two up and heavily laden and I actually had enough preload to stop the front end wobbles. I tried the damping ajuster and couldn't see it made much difference then either....

Hi Steve

When you say 'realy wound up' how much

Catherine and I are off to Ireland fully laden in July and wondering if i have enough, I think it could do with a bit more just dont know how far to go

I too find hardly any difference with the adjustment screw

You will need to adjust the spring tension or preload. The little screw on the side adjusts the damping and is of little use in these circumstances I find

There are lots of threads here about adjusting the preload or you can pop down here and I will show you what I do, though it is not nice to watch....

However, before you adjust anything get the bike FULLY loaded, pump the rear tyre to 32PSI and strap SWMBO on the back and go for a blast and see how the bike feels. Any shimmy/wobble on the front end? Does the bike feel really wallowy in corners or over bumpy roads (most of Ireland!!) If the bike feels solid, you are probably OK.

I have done it once but not allowing for luggage and the wife, just the wife have you any measurements of the thread showing above the nuts, by any chance ?

I'll have a look a bit later, and see if I can measure it! One must make allowances for the Wife I agree, her luggage is another matter.....

The adjustment behind the LH side panel is for slow speed compresion damping The standard setting is 1 turn back from screwed fully in and there are 2 punch marks which should line up.

The pre load is measured by the lengh of the spring. the standard setting is 193.9mm The other measurement to use, can be the number of threads above the locking nuts about 10 is standard.

The best way to achieve the correct preload is firstly take the bikes rear sag measurements, static, rider, passenger and loaded then make the adjustments as nessasary.

I think the best way to get the RSU off is with the rear wheel out, and then from underneath.

The OE RSU is a tough unit but it is shame it does not have adjustable preload. worth upgrading if you change loads often.

last time I toured Ireland I found the roads really bumpy so I would say it is a good idea to get it set up before you go.
