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 The previous version was outdated and no longer supported.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

NETRA ANNOUNCES NEW VINTAGE RACING SERIES

I am still out of town. Will post a pic when I get home next week. No luck having my wife shoot a pic of the cylinder on my bench. Asked her to text me a pic after describing what the cylinder looked like and explaining where it was and I got back a photo of the clutch assembly that was next to the cylinder! :)
 
justintendo: What does the intake side of your cylinder look like? Does it have openings in the base behind the liner below the intake ports?
 
mine has the passageway at the top corners connecting the intake to the transfers. i can take a pic. the intake part of the liner looks like your pic. does yours not have the extra exhaust ports?
 
Base of my CR cylinder. Notice openings behind intake holes in sleeve, these supply the case directly. My WR cylinder does not have these.

My 84 250WR cylinder does have those ports as the 1983 CR cylinder was used on the 84 250WR when the 250CR went to liquid cooling

My CR cylinder does not have the extra exhaust ports and the intakes are not connected (open) to the transfer ports directly. there are just the extra intake openings in the base that charge the case. Does not look like the smoothest path to me. This cylinder came on the bike this way. It's the first time I am seeing it, got the bike this Summer and now doing prep for next season.

On my WR cylinder the extra exhaust ports are cut into the cylinder, visible if you look into the exhaust port, but they were not cut into the new liner! (This is how I got it from eBay. Description: "84 WR250 cylinder, ported cylinder with new stock bore liner and piston"... yeah well, not exactly!) is it possible to cut the liner without removing it first? Would like to add the exhaust ports and would modify base of the intake side, if it's worth doing, at the same time.

So, the 84 WR250 cylinder should be the same as an 83 CR250 cylinder? I purchased this cylinder (PIC) it is supposedly a 84 WR250 cylinder, but no intake port openings in the base. The rest of the port dims in the liner are nearly identical to my CR250 cylinder.

My 84 wr250 runs way better than my other war's did. I was told here the cr cylinders were used towards the end of the a.c. production.

That is an 82 WR 250
 
There are 3 basic air cooled primary kick husky 250 jugs.

one with no cutout on intake side in the liner dumping into bottom end (82 WR)

one with cutout in liner on bottom end 82 CR and XC and 83 WR

one with cutout in liner on bottom end and two boost ports coming in from sides of reed cage right into cylinder (off side of big rectangle opening) 83 CR, XC and 84 WR

Hope this helps
 
Thanks! That helps a bunch. I'm bummed about my WR cylinder. Looks like it is going to take a bunch more work to update the port spec. I got EBAYED!
 
Not everyone selling Husqvarna parts on eBay even knows what they really have sometimes. As an eBay seller I am one of the most honest about whatever I am selling. I buy Husqvarna parts, not sell them(yet).

At least you have the correct sleeve to work with. As far as the missing ports you can lay them out matching the pattern from the CR cylinder you have, drill out the profile to rough core, then finish profile and depths with a spherical burr until everything is nice and smooth.
 
Yeah, that is how it goes sometimes. I still got a new liner and a new piston for a good deal and the cylinder can be reworked. Knowledge is power and I have more now, thanks to all of you.

I purchased a complete 82/430 wr engine advertised as a 250 wr/mp. The 2087 case numbers are the same.

I purchased a 80/390 cylinder advertised as a 250cc.

People aren't sure what they have. The 430/390 have (9) yes nine cooling fins on the cylinder. I'm not the sharpest tool in the shed sometimes. But call the parts anything they want. But to the gurus here you know what they are. The biggest thing I see wrong now being called is the old cases and clutch covers being called newer. The late 70's stuff doesn't fit the early 80's engines.

yes, it does..and i take it that the 83 cr/84 wr are the only ones with the extra exhaust?
 
Someone told me here my 84 250wr has the cr cylinder. This runs and responds better than any wr 250 I had in the past. I like the extra hit. She stands right up showing off her belly.
 
Because it lost lowend and mid range torque compared to the 82/83 250WR engines. It became more hare scramble friendly but enduro hostile. In case you have not noticed BigBill is an old motohead:) and I am an old enduro rider

Interesting... Dwight Rudder said that the '84 250WR, was the biggest dog he ever rode.

...but wasn't Dwight's bike of choice an XR250? My CR has to be pinned and the transmission rowed to go anywhere. Peaky power but nearly as strong as my 83 KX250 on top. Just more work to keep it there.
