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 The previous version was outdated and no longer supported.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

Head shake/Death weave

Update on my 09 TE610.
Adjusted rear preload for 4" of sag. Increased rear rebound damping (16 clicks out). Bike noticeably more stable. Ran up to 75 mph+. Do notice headshake when behind another vehicle at those speeds. So some improvement, but more work to be done.

Steering damper might be in order, but I want to get the bike setup well before I do that.
 
I read on the TT thread where people commented on the grip of the bars causing the headshake. Something isn't right when grip is causing headshake.

I don't think the 610 shock has the greatest compression or rebound adjustment. At least my SM610 doesn't. I have the high speed compression backed all the way out because I think the damping is harsh. I only seem to use the low speed compression. I think I am at around 10 or 11 clicks out for the rear rebound.

I think you can still add more rear rebound before you get to an obscene setting. I don't think it is a preload setting either, but your adjustment is seems good. I'd only make one setting change at a time. It's easy to get confused if you don't, and not notice the effect of the change.
 
Another thing to consider is tire balance? I've had Dunlops give me head shake at the track and Pirellis ran smooth as silk with the same setting. The Dunlops were balanced, but I think the heavy carcass of the Dunlop rear tire just caused the shock to oscillate more.
