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 The previous version was outdated and no longer supported.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

Has any one here had any luck taper boring carbs? what improvements were noted? How about cutting heads down for more low end??
Thank you:excuseme:
 
There is the process the porting guys around here old enough to have dealt with these type of cylinders called decking. It involves cutting down the base of the cylinder and then modifying the head as the piston comes up higher than the top of the cylinder. That moves the ports down. I have a 78 360 that has been done to but never had a stock one. The stator loosened up and I did an engine swap to something newer. Not an exact answer to your post but I think that is the way those porting guys would tell you to go.

Ya I agree. Lowering the cylinder works great if there's room.

First thing I'd do is get some solder and check your squish distance. If it's large you can install a thinner base gasket and get a noticeable improvement in low end snap and crispness. Depending on what your squish measurement shows, you may or may not have to machine anything.
 
I had a 98 Honda CR250, I did that to. Took .5MM off of the base. Made the bike bark.:lol:

On Maicos, i cut the head and the squish band. Makes them pull hard low to middle.Plug is in the center, makes it easy to do..
