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 The previous version was outdated and no longer supported.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

First, I would like to apologies for whipping a dead horse (old topic). I have scoured the "threads" for consistency and have not been able to find a "true" mixture suggestion. Anything between 50:1 down to 25:1, synthetic to partial synthetic?

History: Yes, I'm new to 2 strokes - yet I have Husqvarna chainsaws that I run at 50:1 (I know, a WR is not a chainsaw). I'm a 4 stroke Honda guy - Have been all my life - but I had to have this bike - so here goes the learning pain.

This question may be premature as I can't give you the jetting or carb specification, but my riding style would be non-Racing. I can tell you that the stock carb has been replaced with Mikuni.

Any suggestions would be welcomed
 
Well.... its good that you realize this is a sensitive topic. Asking the question again will result in the same varied ratios (just ask what oil is the best!!).

Another way to approach this is to start with a ratio like the 25:1 you mention. Take a ride and see how the bike performs. Look at how 'wet' the end of the pipe is. Also, take a look at the plug after the ride, maybe take the head off and look at the piston. Nice thing about Huskys is they don't have a head gasket that needs to be annealed after disassembly. If the plug and/or piston are very black and oily, then go to 30:1, repeat until you find a ratio that fits your riding style, elevation, location, and carb settings.

Let us know your progress - lots of great people here willing to help.
 
Thank You Vinskord - makes total sense to error on the side of caution and then adjust from there. And yes, types of oils is always welcome info. I will update thread with results - thanks again.
 
I would see what Jetting is in the Carb also. How does it run with the current Jetting?
Do you have an owners Manual for the bike?
 
Heres a comprehensive tuning guide for vintage 2-strokes. Its more information than what most folks want but it has what most everyone needs if your willing to take the time to read it and pick out what applies to you particular situation. https://www.klemmvintage.com/mikuni-tuning.htm

I used the tuning guide to tune my 72 450 motor build that runs a VM38 Mikuni and the results were worth the time invested. One other thing I did was change to Maxima Super-M 2 stroke oil. A synthetic blend thats smokeless. Sometimes when I ride I pound my motor, always on the throttle. Occasionally I get adrenaline junky fever when riding so I like to know that the lower end is well lubed. I run 32:1 and ride during the cooler months.

Something else to keep in mind is what cheap and/or excessive 2T oil does to engine and exhaust components. Using cheap or excessive oil will create carbon and oil buildup. A silencer looses its sound deadening ability when covered in oil and on your particular Husky the spark arrestor can slowly plug robbing the motor of performance not to mention it can be a real pain to remove from its location at the front of the stinger.

Do you use oils rated for the above letter combinations? In that chainsaw.

I use oils rated for that in my Husky bikes though I have pretty much gone electric at this point. May have spooge out the pipe. either amzoil sabre pro or Echo red armor at a fat 50 to one like 3 fl oz to a gallon 126 fl oz. I reat it is the additives to a large degree that actually do the work and the oil in the manual does not have the additivesof now.
