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 The previous version was outdated and no longer supported.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

Lectron or stick with the Mikuni

Thanks for all the info, I sealed the barrel and performed a leak down test, as soon as I started to pressurise I could hear air leaking. It was coming from the inlet manifold and would not hold any pressure at all. I was amazed at this as to look at it, it seemed ok so a new manifold it is. problem now is that I have discovered a small crack in the liner at the bottom from one of the intake ports so it looks like a new liner as well, question now is 1) Can the cracked one be re-paired? 2) If not do I fit an 84 liner and do the modifications to the barrel as per the barrel thread?
 
On my '78 cr390 the base gasket was melted from being soaked from the gas liquid level filling up the crankcase. The gasket was soft and mushy. The gas was old and had some stink to it. I have no clue how long the crankcase was flooded. This bike was orginal and complete from the junk yard.

Like my 570,

the mixture screw is only out 1/2 turn out with a 62 pilot.

According to George, I should be using a 60 pilot.

If the balance screw is closer to the cylinder in front of the sleeve it meters the flow of gas on the idle. Delorto carb 4t/2t
If the balance screw is at the rear of the slide towards the air cleaner it adjusts the air on the idle.
 
Yes Bill,

You are correct again!

My 570 is too rich at idle.

+ I read that Dellortos wear the slide and the needle.

According to George I should be using a 60 pilot.

I am planning to get a new slide and needle and a 60 pilot.

I have a parts manual for my bike, it is a reprint I got off Ebay.

Nicely bound as well.

:)
 
my 510 runs very rich on the needle. you can see where its worn down from vibrating at idle. I need a new needle and slide. I must get a new needle and slide. there is a ducati place in Sydney well recommended for mail order dellorto bits. boltons have stuff for the kato's as well.

unfortunately, the rich running has scrubbed the rings so im up for a tear down soon....just waiting for brexit to bring the parts prices down from Andy's

Wrong. If the gasket was saturated with fuel it was because it had already failed before the engine became full of fuel and allowed the fuel to seep in. The engine being full of fuel will NOT cause an intact gasket to fail no matter how long it is left in the engine.
