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 The previous version was outdated and no longer supported.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

SwainTech piston coatings...

NFA1934

Husqvarna
I recently received my WR450 piston back from them-I wanted to reduce the piston/cylinder clearance and this is an easy way to do just that.....Fortunately,my 450's bore measurements indicate very minimal wear,with an initial piston clearance of .006-.0065".The top of the piston received another product to act as a thermal barrier....(likely unnecessary for the plodding old 450 mill).
I'd like to hear from any other members having used this same source regarding their opinions as to whether or not they felt that it was beneficial. 100_1319.JPG
 
Yes,
Very much so. Any time you can delay wear,keep/stop metal to metal friction do it. I happen to be lucky enough to located near the supplier of the product to Swain that you see applied above for the coating. They are using in industrial tools , firearms etc. I have a spent some time over at their new factory shop looking at samples. I plan on having a slightly different product for tranny parts done to the very critical high wear areas of my 430. the third gear dog area, and a couple other areas done. Guess what you can reapply to same areas in future after some of the product has itself wore off. Humm I think can we keep are bikes running for a long time.

Look for future report - on future build for 430 CR engine I plan on doing. They are so busy setting up their business to be the contractor themselves - that I believe Swain is a great source to do the pistons. I will have my pistons done soon in my rebuilt bikes. This product can be applied on a used piston. My pistons are almost new in new bore.

I just have spend so many hours restoring - I am looking at other areas where corrosion and rust get to the metal and costing these areas as well. Axles, swing arm axle, the swingarm bushings, brake shafts in hubs, etc.
 
I have always wondered what other parts are negativity affected as that stuff ears off and gets in your oil etc. and goes through your motor. Not saying it is an issue just wondering.
 
$38 + shipping & ins. both ways..... a bargain when the alternative is a NOS piston (a mere $350 ). Again,I was fortunate that this particular engine had so little measurable wear....Otherwise,it'd been "checkbook & butt lube" time.....:rolleyes:

As the coating wears away,IF it retains it's same properties,it may be beneficial,by reducing friction in other areas of contact(like the old first generation car oil additives).
