• Husqvarna Motorcycles Made In Sweden - About 1988 and older

  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

YSS PD Valves for 40mm forks. Anyone tried them?

First, I really appreciate the information I get out of this site. It is much better than the other sites in my opinion...

Has anyone used the YSS PD valves for the 40mm forks? I tried to get information from RaceTech on gold valves and any valving for the Husky 40mm fork and they laughed. You want what!! Fernando from Husqvarna Parts Australia, has these valves and also makes a custom damping spindle with top out springs like the Maico forks have. If there is anyone out there that have used the PD valve and spindle/damping rod and can recommend them as the fix for the Husky fork, please let me know. Any Aussies out there that have used these?

With Race Tech in Corona, you have to ask for one of the guys that specialize in older bikes. The 18 year old kid that answers the phone may know how to dial in a 2008 CRF450, score you some weed or get you tickets the latest - insert current rock band- Concert but doesn't have a clue what a Husky is much less a 40MM fork from 1983 ( years before he was even born)

I forget the name of the guy there but call them next week and be specific with what you are needing. Ask for the owner. The owner also races Vintage (83 CR480) and he is your best bet if you want to go through RaceTech.

Other than that, is this the kit that Phillip at Husqvarna parts in Arizona offers on his website? But shows that it is never in stock...? I'm interested myself.

Those type valve will improve any old style damper rod type forks. They turn they into small cartage units that have a much more constant damping.

Hydraulic lock style rods also can work better than spring top out rods. You get a little more travel and they can be designed much smoother top out action than a spring.

I've never actually used them in an old Husky fork, but they should work the same, regardless.
 
I've used the kit that is on Phillip's site, it's known as an ATK or HP after market damper kit and it works much better than the stock forks with cut-down springs (3" w/PVC spacer to "0" pre-load) and thicker oil but no near Honda or Yamaha forks. I ended up using 44mm FoxForx with a lot of testing for spring rates (from Race Tech). Another work around is to buy a pair of used post-85 forks, I think these (or a similar version) came stock. I also heard that the HP kits were also made for a time by Ty Davis' company.

Can you buy the 44mm Fox Forx through race tech still? What do you have to do to the triples?

Gosh no! e-Bay or other sites have them come around every now and then but they're generally going for $1800+ with triple clamps (may or may not have stems). The you have to tune 'em or do basic maintenance. Once they're set up de da schizel.

Sorry ... I'm not that naive but the way your previous post was worded it kind of sounded like they were sitting on the shelf at Race Tech.....:doh:my bad!!!

I have read all about these but haven't actually seen a pair..... I found this tonight while surfing the web and lifted the image.... this bike is owned by some guy in Oz ( thanks for the pic Husky Bro ... nice bike:thumbsup::cheers:) are these the forks you are talking about:

Note that this 1980 bike is sporting FoxForx.......+ 83/84 DLS, 18"rear wheel 82 /83 style... which are both conversions that I am putting into my restoration.... interesting front number plate as well..... any idea what it is? And possibly a 1978 390 pipe with heat shield?

That is one great looking 1980 Husky!! Those FOX forks are the hot set up if you could afford a set. It's amazing with the demand out there that someone doesn't make them again. Oh well that's life. Thanks for the information on the YSS PD valves. They might be worth a try and maybe I will buy them soon? I know we are all trying to get the front end to work as nice as the back end. It's tough to beat the Ohlins shock. Mike
 
Ya there are some really well thought out mods on that one! Very nicely done. One of the best I've seen, really. Would be nice to hear from that owner, wouldn't it?

I had a friend who put Fox forks and piggyback shocks on his 1980 XR500, a-way back when (along with an extended/banana Franks swingarm which I've never seen since). The suspension was good but, unfortunately, I didn't ride the bike much so can't comment on all the details. Even then, they were expensive and considered super trick. There was tons of adjustability but, again unfortunately, we didn't know much about things like that at the time so we probably never had them working to their full potential. They do go for lots of $$$ if/when they come up for sale now. Usually, the seller knows what he's got and he's marketing them as such. Keep 'em coming!
 
simmons made anticavitation kits for 40mm husky forks. i have a brand new set. they were the fix for 40mm forks. simmons was the first to make inverts i think.
 
It would be nice to have someone reverse engineer those Simons fork kits and sell them to us poor husky nuts with 40mm tubes. Could you post a picture of your anticavitation kit? I am just curious to see hat all they have on the damping rod. Yes, Simons made the inverted forks for Brad Lackeys 1982 Suzuki RM500 when he won the 500cc world championship. Mike
 
Heres a pic of the UDX 60 forks like Brad Used. These were Rex Statens set. Now on a Maico.
