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 The previous version was outdated and no longer supported.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

Don't get discouraged. Most of the 25 vintage husqvarnas I restored were non runners and I scoured the USA for parts. It was impossible to find new parts. But all that has changed lately.

I hear very positive rumors on how fast the '80's 125cc cagivas were here in the hare scrambles. Great looking job your doing, looks awesome.

Will be fun to see :)
 
did you sort out your piston height yet?
different ways to change power is port timing and rod length, as in rod to stroke ratio because it moves the wrist pin up or down to accommodate torque vs horsepower, you might have the wrong year rod or piston

So I been working my ass of the last days to make this happen. Found out after i cleaned out the crankcase that my main bearings where shot. Local bearing pusher had bearings and seals so i was realy happy about that :) After some frozen cranks, hot cases and fighting I put the piston on. After carefully messuring the old bottom end gasket (there are 3 sizes) I put the cylinder on. Sweet I thought...

Then this happend.

WTF! this is TDC

THEN I saw this

Notice how the water thingy dont match between cylinder and case.

And that sucks! Now i have to get my spare cylinder replated and to do that i have to ship it to the states because no one do that here. But the worst is i was reeealy hoping to ride it around the block within my vacation (one week left) And that aint gonna happen! :( :banghead:

Besides that the local machine shop went on vacation before finishing the cylinder head for my project motorcycle (they had had it for over a month!) And thats why i started on this thing, to have something fun to do.

And to top it of i read on facebook today that an old friend of mine (havent realy seen him for alot of years now) had died. He was the guy who found this bike for me back in the day.

So Im realy starting to think that this cagiva curse aint ever gonna go away! :excuseme:

Sorry for the rant, guess i needed to vent a little.

Your cases are from a 85 or 86 cagiva. You cylinder is from either a 87-88 or 89. 87-89 used an external water port from the cylinder to the pump. 85-86 used an internal port between the cylinder and the cases. I suspect your cylinder, rod or piston may be from a 89 as they had a different stroke than the 85-88.
 
Let's see a pic of the heads combustion chamber. I worked on one of these decades ago and remember something being different with the head?
 
Pre 83 water cooled 125s had a funky looking combustion chamber. 1985-1990 heads all look basically the same except around 88 they omitted the locating pins on he head and made minor revisions to the squish band

I sent a barrel from Australia to the UK for replating - cheaper in the UK by far..

You are right on the money there is a long piston and a short piston
I got 2 out of Italy through vertex for my sons 89 125 project
Yamaha yz125k piston fits the 88/89 cagiva as well I got a bit of info from an old tuner who had a lot to do with husky/cagiva in Europe in the mid to late 80s
He had a bit to do with the big hp 125 motor
I asked him if he build me a motor . He still has all the specs for a 35hp motor
I've got nos crank,barrel just need a good set of cases
 
I bought a 88 wmx125 to restore, I was told by the owner it had a yamaha piston in it, but I have not tore it down yet.

Pretty sure 85-88 uses the same piston. 89 is different piston and rod

I may have an extra set of NOS 88 wmx125 cases. I have several nos wmx125 1985/86 cylinder/piston kits

I have a nos 88 and a nos 89 piston, cylinder, rod, head kits I can measure if need be
 
Your engine is a 1986.
since 1987 the cylinder has water passage outside.
1985-1988 the bike mounts the short connecting rod and a piston along.
In 1989, the rod extends and the piston is short.
nothing forbids you to mount the coupled piston rod long and short on your 1986.
the motor runs stronger, was done well in competitions.
 
Nice interesting build please keep the pics coming, I remember these Cagiva 125's being raced and doing well.
 
Bike was put away due to other money pits :mad: And the lesser conscious part of my mind suppressed this thread :thinking:

All i can say is THANKS for the clarification :thumbsup:

I was randomly browsing through ebay two days ago and found a cylinder sleeve. After a bit of searching i hit buy now, hoping its the right one :)

So now there is hope. ooh also got the correct usd forks on :thumbsup:
