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 The previous version was outdated and no longer supported.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

currently giving my 82 cr500 a bit of an overhaul and the original 44mm slide is quite worn . i was planning on buying a complete new carb
there is plenty of debate on carb size
few people in the know have said put a 38 on it
net seems to like 40
i quite like the way it makes power now . im 6'2 and on the large side and we mainly ride big open tracks and not all that far from sea level

is a 38 0r a 40 going to shift the power all that much ? or just carburate better ?
cheers guys
 
smaller carb will develop higher airspeed through intake at given revs. this equals better atomisation power at lower rpm. thats why v8's have vacuum secondries to limit air untill airflow is sufficient to atomize the fuel on all 4 barrels. So 38 will give great instant response but may leave thetop end slow if the engine cfm is more than the carb canflow. if your on long tracks, a 40mm and slightly higher gearing may be anadvantage. giving better mid torque to pull through a coupleof teeth less onthe rear sprocket. carbs are cheap, try one of each. the jetting willbe closefor each carb. the 38mm and a bigger well packed mufflerwillboost mid range strongly allowing you to shortshift a bit more but wont revright out. up to youtosussout thebestcombo...
 
I went back to a 40mm from a 38mm on my 84 500CR, as i couldn't get it to run right. I talked to a few 82 500 owner & they
always complained about the 44mm made it hard to start.

cheers for the imput guys . yeah i under stand the whys and hows of intakes and speed v flow and all that . yeah i dont have much trouble starting it now . fuel on choke on turn it over a few times then find the right spot and kick it hard enough to spin it over 2 revolutions .
putting the boyesen reeds in it and packing the muffler properly really woke it up sooner .
think ill stick with the 44 as i dont want to turn it into a tt500
