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 The previous version was outdated and no longer supported.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

Hello am looking at getting a 390 auto.
Just wondering if there are lots of issues with them?
Whats parts like to get?
Looking for some info / articles on them.

Cheers Rob
 
Main problem on a 390 is engaging drive, the gear and shaft wear quickly. however once you ride one you might think the coming expenses are worth it!!
 
Yes, they are a bit more expensive to run than a 6 speeder. But Steve is right, the extra expense is worth it. If you get one, strip the box and check it (it's so easy). Make sure the sprags are not falling to pieces and the surfaces they run on are smooth. It's worth replacing the mainshaft and dog gear on the end as they will chew up easy. There is loads of info on here regarding what else to check.
The oil is critical. Change it after every good ride (there is only one litre). Every other good ride pull the side cover and re-do the grooves in the clutch shoes.
Since i have built mine, I have no issues at all (touches wood !). It is one of my favorite rides. I have a similar 390WR as a six speed. It doesn't get ridden much now ;)
 
Most of the problems and "bad" reputation you hear about on the autos is due to riders not educating themselves on the correct way to maintain them and ride them. Lot of the problems are self inflicted by the rider. I have been riding the 360, 390 and 420 autos for over 15 years and the only problems I have had is 3 broken 1st gear clutch springs on three different occasions and two of those were from a bad batch of springs that were not heat treated correctly. They are by far more fun to ride than any of my other manual shift Huskys. When I go riding and need to decide which bike to ride one of the autos is my first choice especially when it is wet and snotty riding in the spring.

If you do purchase an automatic and do not know the history on it I would advise you to take the motor and trans apart to inspect it and replace items that are worn. After that, if you don't already, you will have a better understanding of how the transmission works and will last a long time.

If you need help and info this is the place to get it, lots of knowledge here on this site and auto riders.

The nut on the primary clutch is it really torqued to 110nm it seem's allful high i dont want to snap the end off. I did that once on the mag side on a 360wr because the book said 70nm.:banghead:
 
Mine is 90Nm. Never had a problem. Just make sure you hold the primary clutch correctly. I put some pictures of my home made holder on the rebuild thread I did a while back.
 
On my 420's I torque the clutch hub nut to 120nm/ 85ft,lb. The reason that I do is because on the 420's the thread and nut is the same size as the 430 auto's and Husky increased the torque spec on the 430's. I have never had a 420 clutch hub work loose. And never stripped the threads. The 360/390 auto's have a smaller diameter thread size and use the 90mn/ 65ft,lb.This is also what the 420 assembly manual also called for but was just a spec carried over from the 360/390. Go with 120nm/85ft,lbs and you will not have any problems.

Also after you get the motor running again. ride it for about 10-15 minutes to get everything good and warmed up. Then let the motor cool down to "room temperature" and pull the clutch cover and re-torque the nut one more time and you are good to go.

I finally got to look at the bike running and to me it seemed to rattle a lot.
Is it normal for the gearbox to be like that?
I rode it the shifts were smooth and seemed ok.
 
They are noisy,make sure you have the idle as low as it can be before engaging, I set mine so it almost stalling then turn it back up once its in gear
 
Going to look at an Auto tomorrow. Guy doesn't know what year. Thinks maybe 82-3. Says $200. He got a bunch bikes all at once from a sale. Six early 70s CZ's and boxes spare engines. Those are already sold. This could be interesting
 
CZ stuff is rough. Really are six engines. The two chassis are 72-3. Lot spare engine parts in boxes. To the restorer bet lot of those parts are useful. Guess the buyers for all of that didn't take it. Couldn't agree on price. The Husky auto is twin shock air cooled. Beyond junk. The lower engine cases looked good though and complete. No plastics at all tank was aftermarket and all broken. Must be 80-81 era. Think I seen better bikes at the scrapyard. Was worth looking I guess. Like to find a 86 liquid auto that's complete and runs****************************************!
 
A little weird to ride at first, when it free wheels, but your love it. But like others said, ride it 1st, i bought a suppose riding bike,
that was hard to start, and it turned into a mess.
