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 The previous version was outdated and no longer supported.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

My thoughts are I use standard heavy duty non "0" ring chains on low horsepower bikes. I feel the "0" ring chains take up too much power to turn. I run the "0" ring chains on the bigger bore bikes.

What are your thoughts?
 
O ring chain is obsolete It is the second generation of x ring chain now. The old standard chain gets 100 The modern chains get way more than that. Kind of like the treadwear number on passenger vehicle tires, way more now than the 100.
 
I'm out of touch with the newest stuff. I generally use an o-ring or x-ring chain for anything that sees a bit of mud. Fran...k, does the 2nd gen X-ring have lower drag? Better sealing?
 
I have used DID VM x ring many times now it is replaced with something somewhat better. I think less drag and a higher lifetime number rating. I have yet to get the new stuff. With the DIDvmxring the atv product was heavier but the tensile rating was less. Kind of have to be careful exactly which variant is being discussed.
 
if its important to have that extra1 hp at our age that's fine...I just use a normal o ring...just replaced one after 5 years of riding
 
Here is a link to Busting Motorcycle Chain Myths - Story by Greg Burns, Mechanical Engineer, Dirt Tricks Inc.

The summary is a real eye-opener:

"Considering that the average speed around a stadium motocross track is about 30 MPH, we can say that the average horsepower loss between a sealed and unsealed chain is approximately 1/50 of one horsepower.

Considering that modern 250F motorcycles being raced generate about 42 horsepower at sea level, 1/50 of a horsepower equals one-two-thousandth or a 0.05% change."
 
Whatever is on special o or x ring local shop has bargain bin of old stock so will grab whatever is available, might be better off putting a 19 inch rim and lighter tyre on the small bore.
