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 The previous version was outdated and no longer supported.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

My '83 430wr had tractor like torque. Point it and hang on it would take you anywhere.

I been wondering how close are these balanced?

Who does 2t engine balancing? I'll bet the factory rides are balanced.

funny but there is supposed to be a guy in the town i recently moved to that specializes or at least is very talented with balancing the 500 engine
 
They have done couple for me. Last one was 144 and vibrated.
After they balanced it with the heavier piston. That engine spooled back up like a 125 and had zero vibrations.
 
Kevin Cameron of cycle world and cycle magazine has written great articles on engine balancing and everything else. I believe he wrote that a single cylinder can never be balanced if there is no counter balancer but the balance factor can be changed to more up and down motion or more to front and back and this can result in less or more vibration that we "feel".
Interesting note from Canam shop manual 1977 - crankshaft balance factors are pretty much all over the map

175 TNT 55%
175 qualifier 50%
175 MX 27%
125 qualifier 40%
250 all models 35%
 
A few years ago it was mentioned that some of the 400LC crank cheeks were not concentric about the crank journals. Just turning the cheek ODs concentric reduced vibration significantly
 
no doubt, one of my 400 engines is butter butter smooth and very willing to rev. i wish any of my other swedes felt like it does/did. another 400 i have vibrates a bit.
 
The fastest bike I've had was my '87 430 XC, but let me explain...
It started life as a '87 250 XC but my friend Craig Hayes had a 430 top end laying around so he mated it to my 250 XC bottom.
After some secret porting, matching and polishing, Pro pipe, I had the fastest bike I've ever ridden. Easy triple digit bike.
I sold it to my bro who races it every year and loves it.
 
O my goodness , I never knew you could do that. So it would be a stroker 430 ? My 250 has no problem lifting the front end off the ground at any time especially down low and traveling in 3rd or 4th gear . Just carefully open the throttle and here comes the front end, so smooth and with no effort at all. I could not imagine how a 430 that will twist up act . ( a true desert racer)

That's exactly how my 430 feels. .Crack the throttle, the rear tire shreds and the front ends lifts. Effortless. Ride it like a guided missile.

Yep I've seen that in my 400 and 240.
Balanced my 86/240 which was way out and now it's like a 80 on steroids.
Bit hard to ride when the back wheel is spinning all the time but full on outrageous fun.
Sort of like a semi controlled crash.:D
 
It is ridiculously fast on top, but can be a handfull in tight woods.
My bro does very well with it in Illinois H/S and GP's.
 
Fast bike I owned was a 81 KTM 495 :eek: , the 495 had NO reed value, so it would launch, the bike like no other, 84 Husky 500CR, was probably just a fast :D but way more controllable

81/495 KTM was the fastest dirt bike ever built and holds world land speed records to prove it.
