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 The previous version was outdated and no longer supported.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

I just picked up another AC 250 cr cylinder and head. This way I can get a head start on doing the compression release and port plus bore the cylinder. My question is what brand of piston do you guys perfer?

Piston clearance??? Air cooled 250?
 
You are going to put a compression release on a 250?

I have used both Wiseco and Wossner pistons with equally good results.
 
I would go with Wossner over Wiseco. I did not have a choice on my 86 400WR so it got Wossner while the (3) 250 pistons I bought were Wiseco. I found the bore was so out of round on the 84 250WR that it went from STD to 2nd over on the first overbore it ever had.

If you are already at 3rd over and out of round, it would be best to resleeve IMHO.

Piston clearance is defined by the piston manufacturer as they would best know the expansion coefficient of the piston.

Save the compression release for an open bike. If you need one on a 250, then you over built it
 
wossner...use the clearance on the box it comes in.
condition of the bore determines what size piston you need, but you know that! you should have no problems kicking the 250
 
Just get the bore checked for ovality Bill. I had that issue on the 390 Auto. It was on original bore, but inspection found it oval. So we ended up going to 2nd over to get it back round again.
I like Wossner rather than Wiseco. But that is just my preference.
I would only sleeve it if I had to.
 
At 64yo and after two knee operations I just don't have that snap or zip to kick it.
I figure after I installed a Suzuki compression release in my 86/400WXE I could just start it 20 years ago.

I know there's a vision in your minds saying get a 2015 2t 300? My son says the same thing. Eeeeeelllllcccctttttrrrricccc ssssttttaaarrrrt.

Yup my pics are,

Honda. XR650L dual sport.
Street bike Suzuki 1250 bandit.


I was thinking the left kickers would take me for a hike in the woods. People don't realize the bike is my legs, a 2t hoveround?
Maybe a husqvarna 2t 300?

My son just picked up a kawasaki ninja the model similar to the bandit. He sold the 750 GSXR. The Kawasaki is an uprite seating. Not the lay down race bike. My point is she's a Purdy one.

Great news from a urologist today. My cancer is "0", yup ZERO they can't measure it.
He said it was a very aggressive cancer. I'm done with injections. I told him everyday is a gift now. It's time to ride. It's time to look at the world through a visor/goggles not a plate glass window.
Years ago I was on a Suzy ts185 on rt73 going through the green mountains in vt. No matter what bike were on its the same view.
I thought I was on a cloud enjoying the awesome views of the mountains and the blue sky. You just don't get that view in a car. Being on a bike in the country/mountains makes us feel so alive. Or being at the beach to see what the hottest bikini color is today. Everyday the color changes. Better views from a bike. It's almost time to burn up some tires.
 
The 83 CR - XC is AC wile the 84 CR-XC is LC. The WR 83 and 84 are both AC, however the porting is completely different between the two years. Just thought I would pass that along. An easy way to tell an 84 WR cylinder is to look at the Intake, if its got a couple of extra boost ports near the top, then its an 84.
 
My 84 wr has the cr porting I been told here. It also had the two slotted ports under the reed cage area at the base gasket. This like super charges the intake with more boost thus cr porting. I seen the two slots at the base area so I'm sure it's a cr.

I have the 250wr is still assembled, the 430cr is apart, the one is apart but not complete yet. It's either going to be a 420cr or wr I'm not sure yet.

In another month or so ill start browsing for new bikes.

The 250 XC and WR were both AC for the first half of the '84 year selling off leftover '83s with '84 tank/seat/sidepanels. The second half of '84 all three models of 250 were LC.

I've mentioned this before, your bike does not have a CR cylinder, all '84 AC 250s had the same cylinder, the one yours has, there was not a different cylinder for the WR and CR in '84 AC 250s.
 
Well it's going to have a cr cylinder now. It's std bore but needs the next size. It has the extra cr ports. I can't wait to get to port it. She's going to be one wild and crazy ride for an old bike.

It could have an air leak so I'm miss reading it's difference in hit and power. My normal 250wr's never hit like the 84 does. They ran good just not the cr hit.

BUT were all the same cylinders cr or wr?

It's been said here they were using up the extra AC parts as they changed over to LC.
When I remove the head we will see what it is. I'm baffled by the way she runs.

I think the best setup would be the cr porting on a wr tranny. The older "Or" tranny was the best. The first three gears being "WR" and the last three gears being "CR" kept the rpms up in the meat of the power band at any speed with no wr bog if we shifted it too soon.
 
Ok all the AC cylinders were the same. What port timing did they have?
Where they all cr ported?
Where they all wr ported?

It's 1 degree here so I can't run into the freezing shop where my bike is to remove the head.

My cylinder I just purchased is a cr with the extra windows in the cylinder and the extra charging slots on the base. A quick inspection shows there's lots of cleaning and smoothing of the transfer ports besides working on the width of the ports and changing the port timing.
 
The AC 250 cylinders in '84 were IDENTICAL no matter what model. Same port layout, same timing, everything, they did not have "WR" or "CR" cylinders that year. I dont know how much more clear I can make it.
