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 The previous version was outdated and no longer supported.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

Anybody Know how a 166-p8 needle seat compares to the O.E.M. 166-R2 ? Halls has no R-2 in stock. Will try a bigger idle jet to see if it helps initial throttle bog. If jetting changes don't show any improvement , will have a leak down test done, don't have what's needed to do it here. engine showed no signs of external leak.
 
Needle jets go in alphabetical order, lower is leaner, and within each letter they go numerically lower is leaner. So it goes Q-6, Q-8, R-0, R-2, R-4, R-6, R-8, etc. P-8 is way too lean. Get needle jets from eBay or you can order them from any motorcycle dealership, have them look in the Western Powersports or Parts Unlimited catalogs.

The pilot jet has no impact on initial throttle bog, the pilot jet ONLY impacts jetting at idle with the throttle closed. As soon as you crack the throttle slide open even the smallest amount, now the fuel is metered by the slide cutaway, needle jet and needle position. If you have a bog an initial throttle opening, one of those is what needs to be changed, assuming there is no air leak.

I am almost 100% certain you have an air leak.
 
Kartwheel , Thanks for the explanation of letter / numbers sequence on the needle jet. Received bike with the wrong jet. Will try to find the R-2 and change out & adjust.

you do not need to buy parts a common mikuni part from a supplier like halls, any online carb shop has them. these vm roundslides are very common, plentiful parts.
