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 The previous version was outdated and no longer supported.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

Brother build.. 1986125xc/74 450cr

As the title states my brother and I have decided to build a vintage Husky.. neither of us know much of anything about dirt bikes, but he has a passion, and I'm slightly mechanically inclined.. or at least good with research.. We were told that we were buying a 1986 125xc, engine was in pieces but the bottom end is complete.. top end is missing studs and maybe a few other parts I haven't found out about.. every frame ID/engine ID list I've found says our bike is an 86 250xc, no big deal, but a 74 450/460cr engine.. first question, is there anyway to tell the engine size by looking at the engine?? Before we start buying parts I want to be as sure as absolutely possible I'm correct in it being a 74.. second question, shouldn't most parts for the 450/460 be the same? I'm guessing that to get the 10cc boost its a slightly bigger cylinder/piston on the same bottom? We're both rather new, and what I've learned has been learned the past few weeks reading hours on end.. any help would be greatly appreciated, as we want to do this build properly, and restore this bike back to, or as close to factory as we can20160817_222303.jpg
 
Just measure the cylinder bore and that should tell you the size of engine. The second question , is yes bottom end should be the same.
Whats with the 74 engine your post is a little confusing?
There is also a number on the 86 motor that you can look up as well (should be) unless some one took it off .
 
Post pics of the engine stuff you have. There is not much of a chance that you'll be putting a seventies engine in the 86 frame without serious and pointless modification and fabrication. The seventies engines are all air cooled and you have a water cooled frame. Let's see that engine and all the vintage savvy guys on here should be able to help id what you have. This is the best source for any husky info and a lot of these guys have tons of knowledge. Welcome to the world of huskies and the forum
 
Sorry for the double post, this is all from my phone. As I said, I mentioned '74 because that's the year I found to match our engine ID. I'm trying to get pictures uploaded now. I found the bore size on the piston, but don't have anything to compare it too. We really are new to this. The guy we bought it from says he knows for sure it's a 125, and I'm guessing it is at least 80s because it's water cooled.. 20160827_151012.jpg 20160827_151114.jpg 20160827_151030.jpg 20160827_151022.jpg

Thank you sir..

Next question, I can't find what size cylinder studs this bike requires.. main component that I've noticed is missing.. and we haven't been able to find a radiator for a 125, so purchased one for a 500.. I'm assuming that it should work, visually it looks identical, and mounting should be the same seeing as how the frames are the same for the sizes.
 
The engine is definitely an '84-'86 125. Impossible to find parts for that engine, which is probably why it was not rebuilt in the first place.

I would be interested in buying the engine if you want to sell it.
 
An after thought/question, brother wants to know if we can swap the cylinder/piston/head to a 250.. I know you can get big bore kits for newer bikes, but I'm not sure if this is to extreme a jump in size.. if it can be done, how big can we go? And back to the cylinder studs, if anyone can point us in the right direction it would be appreciated.. I've been on every website I can find searching by part numbers and have had no luck..

he should be able to swap in 250 and up motor and exhaust right?anything else unique to a tiddler?
 
no offense but i have thrown away many pistons that looked better than that.

80's 125 stuff is tough to find. trust me.

sugest finding a single shock water cooled 250 motor.

must be a single shocker water cooled though

exhaust routing and rear engine mounts will prevent a use of an earlier air cooled motor
 
I have a 85 cr 500 motor in pieces if interested. Cases are good. Tranny is a 6 speed out a 250. Could find a 5 speed for it if you wanted. It was torn down for inspection and rebuild but never made it back together. Pm me if interested and I can give ya more info. I'd have to check what size bore is as it was my fathers who is unfortunately no longer with us and I don't know a lot about it but can find out any info ya need. Just sitting in a box and I've got 7 other huskies that need much attention.
 
So we've ordered a few different parts, hoping we found studs that will work, got a new kickstart lever, and the internals for it.. anybody have any thoughts on Namura pistons? Besides a 200 dollar original with bad pictures, it's the only company we could find for a replacement.. I wanted the original, but money is a little tight..
