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 The previous version was outdated and no longer supported.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

Auto compression release

I have a low hour 06 TC510 with an E-start and 07 updates. It would start first kick after warmed up (HS starts). Last time out I couldn't start it by kicking and there would be a slight kick back where there was not one before. Slow circuit jetting may be slightly off but it didn't matter before. Any ideas? Thanks
 
If you're saying that it is difficult to turn over or kick then yes something could definitely be wrong with the auto decompress.
 
so how does the auto decompressor work?

The thin "lobe" beside the right side exhaust cam on my 04 bike seems to sit away from the cam when its stopped.
I thought it should sit up against the cam when stopped or cranking and them move out of the way when it fires?
there's a small spring loaded pin coming out of the side of the cam that pushes it away:excuseme:
 
My 08 failed at very low hours (@10) on a Mex ride (what a pain), so "it can happen"
for mine GP motos just replaced the mechanism and it has been fine ever since (100+ hours). R
PS sounds like the same issues mine had as it failed.

Yep, the lobe you are talking about is the decompression release. Centrifugal force spins it out of the way after a certain RPM. If it wears or is not working right it may be very hard to start your bike. Then you would have to do the routine like on an early YZF and get the piston just past DTC.
 
so at rest when you have the valve cover off where should the decomp cam sit? It has to be up against the cam proper doesn't it?
Any thoughts why mine would sit away from the cam?
The pin seems to push it that way.
Pretty sure I have a problem as the electric start wont take it over compression anymore. :banghead:
