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 The previous version was outdated and no longer supported.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

Best of the late sweetish big bores for everyday use ?

you could.....
1. retard timing a tad
2. drop the needle 1 clip
3. try a larger bore muffler if you can find 1 or try repacking with steel wool.

leaning out the mid will soften the hit onto the main jet. I thought you had some richness in the system to be able to do this. obviously you need to test it to make sure its not too lean.

Thanks Surprize,
My manual states 2.2mm BTDC, I am running 1.8mm, may retard a little more.
I thought leaning the needle would make it worse?
Muffler has a very large bore, freshly packed with proper packing, my experience with steel wool is that it will burn and throw sparks unless stainless steel wool is used.

no if your rich on the needle, the motor hesitates (loses power due to poor carbying) then as it comes onto the main jet, it cleans up and you get a rush of power. worth dropping the needle to see how it responds....never seen a twoie send sparks... fourbangers yes..speccy a tnite

I'll try dropping the needle, but it actually felt a little lean coming onto the needle originally with this pipe, a play with the air screw stopped the run on at trailing throttle.
One thing I don't want to do is lean sieze it.


Many years ago I repacked my IT490 muffler with ordinary steel wool, and while not a light show, you could clearly see the red flecks coming from the (stock) exhaust, maybe not a good thing in the summer!

I really like the stock pipe power delivery but my header is beat up on my stock pipe, does anyone know if a header from a different bike, maybe centre port YZ490 header could be mated to the Husky pipe?
Tony.
 
I would suggest if your going to run a big bore a compression release would be handy. Sometimes by the middle of the ride to the end of the ride I could just about put the bike on the trailer. I was logging and in my prime back then. Just a thought.
 
If it were hard to start or I experienced kickback, I'd consider that Bill, what makes you suggest a decompressor for a bike that starts easily?
Tony.
 
Me personally I have a hard time starting bigger bores years ago. I welded in a sleeve in the head of my '86/400 and installed a compression release. I could start it no problem. In time the wear on my joints became worse as I get older.
 
I could have brought the pipe down here and ol mate "Mr Exhaust man" could have rebuilt the header for you no probs. would cost a cupla hunerd bucks probly but he does good work. he cleaned my pipe up nicely.

I should have thought of that! Does he just repair the header or can he replace sections? Mine has been welded poorly in the past.
Tony.
 
he makes full new pipes for Mick down here, so he can make repair anything. could use my bike for a template if required, I think they are the same in the frame pipe dept
 
On second thought, that's probably a good idea if mine has been bent out of shape, I'll call you to discuss it.
