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 The previous version was outdated and no longer supported.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

Porting recommnedations

many are very happy with eric gorrs work.
out of curiosity, what are you trying to improve? have you done any other work to the engine yet?
 
Eric seems like a real straight shooter i'v talked to him a few times once about a 155 stroker KX told me dont bother $1300 stroke job was only good for 1.5 hp but the 144 was good for about 5 i think most builders woulda said oh yea get the whole balla wax

Have done nothing to the motor yet. Referenced the porting recommendations from Husky service bulletins.
Want wider power spread.
Thanks for the input! Any other recommendations welcome,
I did add Race Tech emulators to the forks.
 
The service bulletin regarding the use of an 82 250WR sleeve is an excellent place to start from. The addition of an 83 or 84 WR expansion chamber would complete the benefit

I have a WR that I got for a parts bike. Was unaware of using that pipe on the CR..
 
The bulletin requires adding 20mm to the headpipe of the CR expansion chamber so using the WR pipe would leave your CR pipe intact. The bulletin is good because you can make a Husqvarna unruly by adding the wrong kind of power. It fattens up the mid range and gives a bit more lowend without affecting the CR top end
 
The WR pipe will help some, but no matter what you do, the '82-'84 air cooled engines are never going to have the smooth torquey power of the '81-older 250s. The '82-'84 air cooled 250s are mid-top engines, its just the nature of the beast.

Copy, Thanks. Just looking to squeeze every bit of power out of her. Knew that from racing my 82 CR back in the day. ON/OFF power and work the clutch
Even though it is kinda a cheater racing in the post vint class (air cool, dual shock, drum brake) against the older Japanese bikes. Who knew that Husky waiting to advance into the modern age back in the early 80's would pay off in the 20K's.
P.S. Alabama isn't toooo far from VA. Hopefully we can meet up some time (Budds National or Lake Sugar Tree

My good friend "Rokon" Mike Murphy lives in Callao VA. I've raced at Budds when I was young and serious, and I'd like to make it to the AHRMA race at Axton some time, but I usually dont drive that far for MX only races, I need to have a cross country race too to make it worth the drive.
 
I know that the Expansion Chamber Mounts are different for the 83-4 AC Bikes than the 81-2 bikes. But was the Pipe it self the same Dimensions ?
 
With all my years of porting I found the two strokes kind of know when your going to wick it before we wick it. The throttle response is right there. I enjoy riding a ported engine that comes to life. It's a different kind of response and power. It's all in the twistie. There is no hesitation or slow throttle response the rpms are right there.
