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 The previous version was outdated and no longer supported.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

Wow wonderfuild job!!

One question though as I'm guessing you're planning on riding this quite a bit. Aren't you worried about availability of the clutches? I know you mentioned you fixed your own and what not in the past but to do all that work every 500 miles is quite a bit. I ride atleast 500 miles a year, I don't know how much you ride but a clutch every year can get expensive.

Unfortunately I don't get to ride as often as I'd like, but to create a little longevity I have recently also aquired a 6speed CR500 engine that will be fitted to the frame so I will have 2 motors to choose from.
I have a small assortment of new primary clutch stuff & I'll also be rebuilding the old worn parts in my collection when I'm confined to the shed, so I should be ok for a couple of years.
Getting it registered is the next hurdle & I'm sure that will be an experience to forget as I hate dealing with government departments.
cheers.

I thought you were selling bikes not collecting more?

Did you find the extra cubes you were talking about?

Hi Speedy
Can you send us pics of the porting made on your cylinder.
Here's the answer Paul ( nice guy) made to me when I asked about porting
430 ae cylinder.
Michel


PORTING 430 AE CYLINDER BY PAUL ROONEY

Hi Michel. Ok it is no good porting an auto for top end power as the auto
only changes gear at maximum torque, & only revs out once in top gear. So it
needs to be ported for more mid range power which is of more use.
Exhaust from top standard = 40.mm, take it to 39.mm.
Exhaust wide standard = 58.mm Take it to 64.mm. Keep the sides of the
port as straight as possible.
Square off the top of the inlet booster ports.
Turn the cylinder upside down & drill 2 holes 1 each side of the inlet port.
Drill from the transfers to the inlet & then grind out till you make them as
large as possible & a nice shape. Do not worry if you cut into the cylinder
stud holes as the head gasket will seal it.
Once all this is done then take .25mm of the top of the cylinder.
You will need to go leaner in the needle jet & up one size on the main to
test. Have Fun Paul.
 
My 82 420 is on Historic Plates,that wont work for you as its needs to be 30 years old.Plus there not to keen on major mods.Maybe look for a sympathetic blue slip bloke,good luck with that.
 
G'day from Oz,
Well Micheal I hadn't planned on pulling it apart to look at what Paul did but I'll think about it in the next week while I'm at work as I also have to work out how to make the rear engine mount 17mm to accommodate the 07 swing arm bolt. Im at work for 7 days & I'll try & get some pics when I get back.
Cheers,
Speedy

Gday Michel,
I finally got some pics of the ports for you.

As you can see paul is pretty extensive with his porting, as to performance it now starts very easy & has a fat mid range which has made it really nice to ride.
Cheers:cheers:

Here's a shot from the base of the cylinder.
Cyl 2.JPG

Just a quick update, the bike & I have had a love hate relationship (I loved riding it /It hated my lack of skill in setting it up right) with it seizing due to my lack of knowledge,(too lean/incorrect timing/incorrect plug & not re-torquing) but with perseverance, a brand new 38mm Mikuni with the correct jetting & great help from Paul Rooney, I've been out riding & we both had a blast. Now it only takes 2-3 kicks to start from cold & 1 when hot, I've also adapted an OR390 kickstart to get the frame/footpeg clearance I needed.
I've also had the suspension done & gave it a new set of wheels with black rims which I reckon look ace.
I've also just been given a helmet cam so I'll try & get some video on here soon.

Hi Speedy
Can you explain more what has been made exactly and with some dimensions ?
The 2 inlet central holes seems to have been grown in the down.
Can you send more pics, and from the inside of the cylinder ?
Thanks
Michel

Sorry Michel I can't as its back together & running but I have made the photo's bigger so you can see more detail.
Here's a few photo's of it finished.

& one from the cock pit.

& this is the side of the bars that confuses most,
Nauto 20.JPG

& this is how it looks with the other motor, a 85 CR 500 6 speed.

Note the taller cylinder.
Now to go out & use them :banana:
 
Well I went riding the other day & was having a blast until it stopped, at first I thought it had seized but found out later that a spring had broken & jammed & fractured the outer cover.
So I've made a cover to hold a spring if it breaks & reduce the chance of damage.

I've a question can the outer cover be welded?

here's a few pics.....

Don't know exactly if it is Magnesium or Aluminium, but a good welder can surely repair that.

Nice Video Speedy. Shame about the spring....but you gotta love a NOS sidecover!

Thanks Wayne, the video image turned to crap when it was edited so I'm trying to find a better way to do it.
Love the idea of a NOS cover but it aint in the budget at the moment as I've been out of work for too long so I'm going to a few welding mates to see what I'm able to do.
