• 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 The previous version was outdated and no longer supported.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!

ITC heavy springs

There are new replacement shocks that use two springs like a lot of other bikes in this section. It is Ohlins isn't it? Would those springs fit? I have one set up with two springs, it seems they had one long spring origionally on the itc. Higher spring constant will go hand in hand with more rebound damping. There is quite a disconnect in the weights (of riders) posted in various threads on here and the pictures of athletes in the owners manual.
 
I'm 300# and the stronger preload always worked for me. On the '83 twin pillars.

We need a closer look your upper spring set is closed up?

Did you adjust or check the static sag with you on it?
 
The smaller spring of a two spring setup is the softer spring, it is supposed to be coil bind under heavy compression like landing from a jump in his pictures, when the smaller spring coil binds then it transitions to the heavier main spring. If it is the stock spring for the ITC though, it is not a two spring setup, it is a single progressively wound spring, but the softer section of the progressively wound spring is supposed to coil bind also. The ITCs were all undersprung stock and relied too much on the ITC bottoming valving, but I believe Ohlins has several heavier springs still available for them.
 
most riders in OZ have gone for a yellow 2 sproing set up and all wax lyrical on its performance... I cant afford em yet:(

He has the heaviest option ohlins ITC springs on the bike ;)

Needs to test with more preload :rolleyes:

Come on Steve (Bengt Husky) get it sorted
 
I got the yellow ones brand new and had shocks serviced. Not stiff enough, have to run preload at max. Doesn't bottom often but that is not the way to do it. If someone researches having custom ones made I am in for a pair as long as they are not made of gold.
 
I checked the free sag last night and that is 25mm (1 Inch) I am going to (short term) set the free sag to zero by moving the clips down. I'm also going to fit some bump rubbers to add an additional bit of space. The ITC's don't have the bump rubbers as they have internal cartridges. I found I have smashed a new DC plastic seat base as the rear tyre has contacted badly with the rear mudguard on the huge landings off the big jumps at the Ken Hall Track (UK).

Long term i'm going to look at getting some custom 330mm long progressive springs made and lastly go on the cabbage diet....I may not lose any weight, but any one close to my backside on the track will feel the full force of the gas emmitting from it ...:lol:
 
There are several heavier rate ITC springs available from Ohlins, they are all yellow. All the new Ohlins springs look similar, so just having a yellow set does not mean you have the correct spring rate. Craig at Club Husky just rebuilt my ITCs with new progressive Ohlins springs, he was very knowledgeable about the ITC shocks and I would recommend talking to him. My new springs have the model numbers printed on them, for reference: Ohlins #00180-40 (260lb rider).
At 300# I'd guess you would need #00180-42 / 00180-44 if, available. The ITCs do have bump rubbers stock, these are also still available from Ohlins. ITC cartridges can be modified for more damping, which you will need with the heavier spring rate.
 
There are 8,5mm & 9mm diameter springs for the twin pillars.

At the way I'm dropping weight I should be 250# by spring. The bikes will be happy, happy.
I was 390# last springtime.

I lost 60# once riding a husqvarna cr 390 4 to 5 times a week in 3 months.

steve has the same springs as you ... Maybe his claimed 'fighting' weight of 230 lbs is just a figment of his imagination !!!
 
The reference weight/rate is based on the info Craig told me. I have 00180-38 springs on my bike, I'm 210 and he said they were good for 220 (this is rider weight, no gear). The caveat is the style of track: go up a spring rate for tracks with large, steep faced SX-style doubles/tables-that is, if you plan on jumping them. Natural terrain MX tracks are good with the suggested base rate. "...individual results may vary, consult you doctor".
