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 The previous version was outdated and no longer supported.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

Bored my 360

the bore alone wont be a change really. if the bike was leaned because it was running richer from low compression beforehand, it will be lean when the engine is rebuilt.
 
First why did the piston fail? Find the reason why it failed. Are the seals and crankbearings ok? When it's assembled to a leak down test. Check for air leaks. I let the air leak test run overnight to make sure it's good.
 
The piston didn't fail, it had some slap & the compression was down some so I had the barrel bored. Was afraid it was going to break a skirt.
 
I do not think the half a mm increase in bore should be of concern. If the bore of the cylinder and the skirt of the piston has worn most likely the bore of the carburetor where the slide goes has worn as well.
 
Got the 360 back together, runs good except it craps out at WOT, tried up and down on the main jet, no different from 430 to 400, hate to go any leaner, it had a 410 in it. Set float level to parallel with carb float bowl surface. Ideas??
 
Does it fall flat or does it blubber? Flat is usually lean. Breaking up or blubber is rich. Bore shouldn't change anything really.
 
a bore doesnt change things but a different (proper) level of compression does. what is the stock spec jet size?
 
Probably rich on main due to extra vacuum from new bore would try 380 and do some plug chops.as justintendo said not the bore itself but the fresh top end that changes jetting.
 
Air filter is clean?

Main jet standard size?

Needle and seat isn't leaking?

It balances with the screw for best idle? Between 1/2 to 1 1/2 turns out from bottom. One turn is preferred then the final adjustment, tweaking it has room to turn in either direction.
 
Took carb back apart, blew all passages out, put back the original 45 pilot ( I had put in a 47.5 trying to get it to start better) test rode , no more problem at WOT. Not sure what it was, the richer pilot wouldn't affect WOT would it?

something clogging the main? chunk of plastic or the like?
hard to say..now you wonder if its lean? always have to go richer until you get four-stroking, then back lean a size for good safety
 
bit of pooh in the carb, doesn't take much. drop of water from jerry cans flake of paint etc. I allus takes the bowl drain out real careful to see if anything is in it
