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 The previous version was outdated and no longer supported.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

Ok my brother and I have acquired these two beauties.....

Mine is a 86 430XC (Larry Roeseler) (Niles ussery) "factory machine.... WP upside down forks, flex bars, WR subframe, 7.0 rear spring, trail tech odo...

My brothers is a 86 400XC restored to the nines..... all original....

My question is..... these babies both have 6 speed trannys... I know in the late 80s we went thru a bunch of them.... are these still an issue or was that a bad batch of gears by pissed off Swedes?

Also what is a good compression reading.... his has 160 mine 185....
 
I have the 86 400 and see silver in the oil and change the oil about every 3 rides or 12 hours.
I been inside to look for ugly wear but never seen anything getting worse. I buy type F atf by the pail as its cheaper.
30 to 40 rides a season, all at least a 4 hour hard ride.
160 is normal, so they are both happy and very nice bikes.
I have the same forks on my 86 too.

I think the dogs on the side of third gear is where they wear the most. (prob. the most used under the hardest power) At least thats where mine wore out.P6280483.JPG
 
i have abandoned the use of aluminum clutch discs and with that my oil looks way better now after a ride. that silver look takes a lot longer to come back.
 
Would the Barnett clutch discs with the steel plates and clutch springs be considered the best setup?

i dont know if its best but there arent many options. i have heard barnetts used to be not very good for huskies but i believe they changed their frictions. i have had a set of frictions and steels in my 88 250 all year and they have performed well. good feel, no dragging, and bike even starts in gear.
 
Now what to do?
Change to a new Barrett clutch setup or go with the original friction plates with the Barrett steel and new Barrett springs? I'd like to service the clutch while it's apart. Or should I fly with what's inside it if it looks good? I hardley ever touched the clutches before unless I had some used thicker friction plates.

When the used or new clutch is worn in. On the cnc machines with the large clutches similar to this type of clutch in the bikes we put a notch across the one row of driving tanks so if it's ever disassembled it goes back in the same position in the basket. This was the plates are were they once were no break in all over again. I disassemble a clutch the was the plates come off. And reassemble it exactly in the proper order. Your clutch will stay at 100% lockup just same as it was before disassembly.

I built lathes with 36" chucks up to 144" chucks all these cnc and manual lathes used these clutches.

the tranny issue you spoke of had more to do with the late 87 and then all 88 models as yes it was some pissed off Swedes
the dealers were taking them apart and finding things in the gearboxes

I blieve some of the earlier 400 water cooled bikes had a higher compression head than the later ones that just had a 430 head not stamped 430. That is what I found but real limited sample. On might study the parts sheets and see. Less bore and same head would seem to me to lead to lower compression ratio all else equal.

It is hard to find a third gear that doesn't have pitting on the gear faces or engagement dogs less than ideal.

4th 5th and 6th are the same for all if not most of all 250 to 500 six speed. 430 wr,xc and 500 wr,xc same third as continued on in next section early single cam or something like that.

I believe the gear I picture was sourced during the BMW era. It is from cz.

does anyone know which early nineties four stroke transmissions swap to the 87-88 swede? i see them on ebay and they look really freaking close but am scared to drop 100-200 to find out its wrong..would also open up a nice mod to the 5 spring clutch swedes to go to the 6 spring setup

On my 88 430, I found a snap ring not seated on one of my trans. shafts & that caused it to pop out of third gear. Must of been from the factory because I know the history of the bike.

I bought a second hand 400 head out of the USA and the the compression was way up compared to the Australian one I was replacing.

transmission swaps fron 87-88 use many of the same parts up to a 98, not sure of the difference on the shaft but most of the gears themselves use the Swedish numbers
5 to 6 spring swap, first off you need a six spring clutch cover, 2nd if you properly shim the shaft you can swap them in, the 5 spring uses a clip to hold the clutch and the 6 spring uses a nut we put a 6 spring in my brothers 85 CR500 and it worked fine, but if not shimmed properly you will not get the clutch to disengage
 
interesting.. theres alot of nineties parts out there.
you are saying with shims you can install the six spring on the older circlip style shaft?
