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 The previous version was outdated and no longer supported.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

250-500cc FMF Gnarly question

Hey guys,

I just pulled the FMF Gnarly pipe off my bike because it's beginning to leak at the exhaust port. I see it has the typical double O ring and copper gasket set up. But, I was looking at the at the parts diagram for the stock exhaust and it looks like the stocker has a different set up. It looks like one O ring and a washer ahead of the pipe. I checked FMF's site and there are no O rings listed for Husky's. Can anybody tell me what to use for replacement O rings and crush washer?
 
since the port is the same size and Husky did the math for temperature rating on the seal I would go with two stock ones and call it good
the "crush washer" is to keep the steel pipe movement from destroying an aluminum port, use the stock one
aftermarket pipes are for tuning and typically they see you using oem stuff to fit it
 
i ran across fmf exhaust "o-ring and spring" kits on e bay- they listed none for huskys, but a bunch for all the jap bikes-all you have to do is figure out what bike has approx. same size exhaust port and u should be good. (they are rubber o-rings,probably not a precise fitment) didnt see any crush washers.
search "fmf o rings" in e bay motors. good luck! hope this helped
 
McMaster-Carr. Viton O-rings for KTM big 2t's FMF pipes are the following number:
part # 9263K739 (44mmx3mm)

Not sure if the Husky 250/300 have the same dia as the KTM pipes? I dug around on the oring page and figured out the same for my 125 fmf pipe, but can't remember the size off the top of my head.

$15+ a bit of shipping will keep you for a couple years or more, or share them with your buds
 
Thanks! Never thought of that route, I'll probably just measure the ones on the pipe now and order some of those.
