I just installed these on my '73. So far, it's totally transformed the bike. Handling is more positive, braking is crisper, a real joy to ride. I do have to admit the previous set up was a bit knackered, so a comparison of before and after is a bit skewed...

Really nice post, thanks! Great pics, and some great tips. I will have to look into these dampers- I have been asking around as to what I could do about the front forks, this is the first good idea I have seen. Thanks!
 
Thanks very much for the writeup, mine are en route from England and that will help with the installation....also FWIW am a neighbor over in Sonoma Co.
 
After riding my commando for years with a stock set up, I'd like to try something to make it handle noticeably better. Of course these are on my wish list now.
 
Excellent thread, Cheers and Happy New Year!

Am I right in thinking these have compression damping in one leg and rebound damping in in the other.

Doesn't that assymetry cause a problem with different forces acting on each leg?
 
If you mix up your needle top nut, how do you know which damper it goes with. I see that the holes on the lower damper are different from one another.

The longer needle fits the rebound (R) side.

Hope this helps.

There is an "R" and a "C" respectively on the needles. No problem there. But which damper is which?
 
Hello Pommie John, You are correct , force's acting if differant directions are working against each other, BUT they are only a fraction of the resistance the wheel/spindle offers to resist them , The total damping resistance is approx 200 LB,the wheel /spindle's bending resistance is far in excess of this , as stated many modern bikes use rebound and compression in differant side's.

Hi all,
I am thinking of buying a set of these as my forks are really stiff & knock on the rebound.
I think the insides of my sliders are worn & the lower bush on the stauntions are a loose fit & not keeping the stauntions straight in the sliders.
If I fit the Bould internals does anyone know if it will overcome this problem or do I need new sliders.
Ive loosened the wheel spindle so the forks are not pinched together but the forks still dont slide up & down freely like everyone elses.
Any suggestions plaese ?
Thanks Don

Unfortunately the Lansdowne dampers won't transform your worn forks back to "new". However I suggest you have a word with John, as he was developing a sleeve kit for the sliders. post67472.html
 
The other question to ask (Don) is when did you last check / change the fork oil in the sliders.

Incidently, Your welcome to have a ride on mine next season if you like, and then you'll be able to see if you like the big improvement that they make.

As Ludwig rightly state's poor alignment and wear in the slider bore will cause many problems...I am finnishing Unclvins resleeve kit, Which will be set to him soon, the kit comprise's of two steel sleeves that are bonded into the original worn bores.
New Nylon bush's and a New spring kit finnishe's the job off. d
