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 The previous version was outdated and no longer supported.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

Suggestions for a carb for my 510

The 86 510 has a Dellorto on it but it's worn and contributing to difficult starting and poor idling. Who has upgraded their carb on an air cooled 510? The Keihen FCr is a bit much for my wallet.
 
Thanks, I'll look into that. Do you use accel pumps or no? Pumper Dellorto carbs for my Moto Guzzi are similar to Mikunis in price. Would you have a jetting kit for the Dellorto?
 
I cleaned the Dellorto carb again and got a fuel mixture screw. Set the valves and tried to start it. 5 kicks w/the choke and decompress on, choke off, kick, nothing. kicked several times and, still nothing. check the plug-wet. Cleaned the cylinder out and the spark plug. Kicked it a few more times and she burst into life! The idle adjustment has no affect(?). Guess the slide is worn. Changing the fuel mixture had no affect. Got outside started her up easily again and took it for a little ride. Snow on the ground, very slippery but when I hit solid pavement what a hoot!! Very pleased with the power, clutch doesn't slip didn't stall it. Not bad for a $550 bike. New cam chain, reed valve and rubber parts from Andy at HVA.
Sudco sells a jetted Mikuni TM for $250. One with a hot start is $360. Couldn't find a Dellorto with a hot start-regular PHM's run $300 plus shipping from Germany. Leaning towards the TM and maiking a hot start button. Can't wait to get this out and flog it a little!
 
Just found a Keihin 39mmFCR off a Suzuki RMZ 450 for $200. Has a hot start button and accell pump complete with throttle cables and throttle grip! Jetting should be close.
 
I have a pumper carb (off a sport bike) Halls built for a newer 510 I'd sell for a couple hundred dollars. Supposed to work great but I never installed it. Would think it would really wake that bike up. I can get you details and measurements if you have any interest.

I would have been very interested but the FCR has been purchased. Appreciate the offer. Even with a worn out carb she's got balls!
