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 The previous version was outdated and no longer supported.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

Anyone have experience setting up or running a boost bottle on an '82 430? I have a complete system (bottle and Mossbarger reed assembly w/pipe) from the Pro Circuit era, just don't know how to set it up (jetting) and whether or not it's worth the trouble.
 
I think this bottle would add more power...

Jetting Info

When installing our reed cages, the engine will generally run" RICH" on the low end, due to the increased air/fuel flow from our more efficient design. The following jetting guide will start you off in the right direction.

1. Lower the pilot jet size by 1 or 2 sizes smaller.

2. Raise the main jet by 1 or 2 sizes larger

Note: steps 1 and 2 are very important in that, if you lean the pilot you must richen the main jet. This keeps the same amount of fuel going to the engine.

3. The pilot jet is the correct size when the engine pulls hard in the lower ranges, and runs crisp and clean.

4. The main jet is correct when the engine runs smooth and clean in the upper RPM ranges. It should not be lean, As all 2-strokes run better with a slightly richer jet setting.

Note: The sparkplug should have a DARK BROWN color on the insulator




MOSSBARGER POWER GROOVE REED ASSEMBLIES
With all racing engines, the more air you can flow into the cylinder at a high velocity, the more power can be obtained. Below are measurements of different reed valve assemblies measured at 10" of pressure drop, with all figures corrected for temperature and humidity. Note that CFM is cubic feet of air per minute.
