HI All !

I would like to "stiff up " the front end of my ambo , i was wondering if anyone ever used these springs ?
are they worth the money ?

Or should i just used a thicker fork oil ?

Thanks a lot for ,

I've never used those springs but, I have seen spacers placed on top of stock springs. You can use PVC, there's a union that fits perfectly. I'd send a picture but, I'm away from the shop for the next week. Hit your local building supply store, I'm sure you can find something.

I also cut spacers from the hard pvc, most likely around 3/8" thick, and use 20W fork oil. Make sure you grease the springs up too, just like factory did.

Thanks guys , looks like the best idea and cheap too  :)

question: how do i pull those forks out of the triple three ?

I took the head light off, took the bolts that hold the fork cover off , for cover spit but if i pull down they dont move... i have manuals but it's not clear how to do it.
just asking before make any damage,thanks

I put those in mine.  Great ride!  I wish my Goldwing rode as smooth as the Ambo.

Thicker fork oil, or more preload are no replacement for a proper spring rate.

Back in 1979ish, I replaced the stock 50 pound springs with a set of 78 pound koni shock springs in the forks of my eldorado. Worked great.

IMO, adding a PVC spacer is not the way to go. You may end up with coil bind at full compression, not good. I'd either spend the $$ for the Wirth springs or at least new original replacements. I fill the forks with 8 oz. of 30w fork oil in each leg. The extra oil not only gives the forks damping throughout the full range of travel, but also has the side benefit of reducing the "air gap" and firming up the effective spring rate.

Here's an excellent tutorial on how to remove and rebuild the forks: http://www.thisoldtractor.com/moto_guzzi_loopframe_fork_rebuilding.html

Some folks use a broom stick to pull the tube up, but I find the proper tool is a huge help. One can be made with length of rod and a modified top plug (the hex head is machined off).

thanks again.

I used straight 30w motor oil in my Eldo forks. All I had at the time. So far so good.

Pushing 18 stone, I consider my purchase and installation of WIRTH`s PROGRESSIVELY WOUND FORK SPRINGS an unqualified success  :bow

[Turin]

I'm running wirth springs as well. The ride is pretty sweet!

[nunzio]

I just installed a set of Wirths springs from MG.

I can see where Charlie would like the tool.
He probably works alone and installs more front forks in a year than I will in a lifetime.

I've done it twice in a year.

I use broom handle with two fence staples drove in the end to make it big enough.

I can send you some fence staples if you don't have your own ,though, I can't imagine you not having any!!  ;D

You are  not  pulling real hard.

My wife is a good helper!!!!

We just extend the fork all we can by hand and then I start to pull a little as she lifts up the bottom of the fork.

It takes a couple times.

It's fun when you get it to work....Alan

To take apart and drop tubes, a small wedge in lower tree. I also made my own tool, weld a nut on an old fork cap and take a length of threaded rod bent like a crank(2 90* bends) and screw into the nut. I put a heavy cast spacer on the threaded rod to act like a slide hammer. This tool was in the 1st MGNOC Tips book w/ it came to print.

That's more than 50% heavier. When Ikon replaced mine, they specified 10% heavier. Have not looked back ;D YMMV

I got the springs in today , when install them , should i just grease them up ?

Yes, grease them (and the area of fork tube they surround) liberally.
