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 The previous version was outdated and no longer supported.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

They made a huge BOO BOO

:(I could use some helpful input if anyone can. Here's the issue: On my 09 TE 250 I decided to get my suspension revalved, lowered 2" and have a bladder installed on my Sachs rear shock to replace the piston in the shock's oil tank. So, I got the suspension returned to me friday. As part of the bladder modification, they put a charging valve on the rear shock's oil tank that hangs down about 3/4" more than the stock one did. They left the stock oil tank on the shock. As a result, the charging valve hits the right side engine casing so that the shock will not fit anymore.:mad: The stock charging valve and tank bottom only clears the engine casing by about 1/16". I will contact them tomorrow to get this resolved. Question: Did anyone else with an 09 TE 250 have similiar problems with getting a bladder installed on their rear shock? And if so, what was the solution? I would appreciate any helpful info from other's experiences.

Thanks,
Huskyista
 
Why mess with the reservoir? This is the first I've heard of anyone doing that...
What are the proposed benefits etc.?
 
The supposed benefit or as the theory goes is a more supple shock in reference to square edged things such as roots and rocks. In order to hold back/seperate the nitrogen from the oil under such high pressure a tight seal is required on the floating piston inside the reservoir. Using a bladder to do this job does not introduce any form of stiction into the movement of the shock. Again, it is during these smaller/ faster piston speeds that the benefit is realized.
A solution to your problem is to replace the shrader valve with one that requires a needle to supply the nitrogen. These are way safer than the shrader as there is always a chance of either somebody easily using their finger nail to release the nitrgen or having it sheared off. Most shocks use this method now for that reason. Could you tell me who sells this reservoir bladder and what is the psi of the nitrogen supposed to be on the shock?
 
I forgot something.You will be able to have this work done locally as there is no need to open up the shock to replace the valve. Do you live near any snowmobile shops that would service say Fox shocks for instance because the fix I'm thinking about could be done using a readily available part off a comman Fox shock. Let me know if you need help.
 
It's been a while but on a KTM 200 I had a few years ago I did the install of a bladder myself and it made a nice difference for me. My issue always is the same as I only weigh about 150lbs and roots and rocks give me fits with my bikes deflecting instead of absorbing these small hits. Since I opperate a side business of rebuild suspension I have all I need to service this stuff so it was an easy decision but if I had to send it away I might think twice about doing it.

This is a typical schrader valve

And this is what I'm describing.
 
It's a needle type charge valve. I'm not sure why you would want to go that route. I use KYB bladders and bladder caps that come off at an angle.
 
I've had this done on both my Huskys. In both cases they replaced the end peice that the Schader goes into. The combined new end piece with new schrader valve does not protrude past the shock reservoir.

I don't know who makes the bladder. They pressurized it to 165 psi
 
Thanks everyone for your input. I spoke with the shop and they said send the shock back and they would fix it right for free. So, I mailed it today and we will see what happens. I had hoped to be riding by now, but such is life.
 
All seems well now:). Pro Action put a recessed cap on the shock free of charge and did it with a 48 hr turn around time. It fit fine and I have one ride on it. The revalve didn't make me faster, but it did make the bike easier to ride. It feels like it's "my bike" now.
