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 The previous version was outdated and no longer supported.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

have just picked up an new issue of dirt rider magazine and i has a picture of their first issue with a 82 husky cr500 in the throws of passion in the front cover . anyone know where i could find a digital or hard copy of the entire magazine or article

its an awesome photo btw

also while im at it .

same bike . previous piston had to be relieved coz it was hitting the head . putting a new piston in it currently . will check squish . what should it be ? and how to adjust it properly . base gasket thickness ?
 
Head Gasket Or Base Gasket Will Work. My Modern KTM Used Head Gasket Thickness To Control Compression, It Was Common Place Racers Looking For More Power To Not Account For Heat Expansion And Smash Pistons.
 
Here's the cover.. i've got the issue too, just not sure if my scanner works any more.

High compression not always the ticket for a strong engine. Something that breathes and turns well often performs better all round.

1,5mm good allround squish on Husky bigbores, giving plenty compression.

Min safe squish on 500 is 1,2mm measured cold with soldering wire through plug hole, both sides of piston simultaneously in line with gudgeon pin. Obviously big-end, small-end, mains in perfect condo is a must.

At 1mm piston starts smacking the head when over revving, pinching the ring. Experience taught me this one.

AC you adjust with thickness of base gasket as head is a lapped fit directly to sleeve. On original 83/4 barrels a base gasket with 1mm thickness after torque gives the crown of the Mahle piston level with bottom of transfer ports at bdc. This is your starting point. If its been re-sleeved, or material removed from the top of the sleeve then matters get more tricky.

LC you can play with top and base gasket thickness and affect port open duration even better.

Far as AC heads go, some had a small step where it faces onto sleeve, some not (like on a 84 short stud, high compression, head i found). This will obviously affect squish.
 
huskyhamm thats exactly the answer i was looking for . i understand all the factors involved but its always best to ask people who have been there and done it on the same brand before . thanks man .

husky john, has the article got much to say or some cool pictures ? maybe you could take photos with a camera and email them to me and ill send you some $ unless you feel like finding a scanner and uploading them to somewhere . (some people have photo bucket etc and some dont )
thanks either way
