  • 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 The previous version was outdated and no longer supported.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 petcock rubber o ring - what's the trick?

Hi fellow husky riders. I noticed a fuel leak from the petcock after my last race. I've removed it and cleaned away the crud that was built up but now when I try and tighten up the petcock to the tank the rubber o ring/washer keeps moving/squashing out of one side as I tighten the two screws up. I wouldn't even say I'm over tightening them screws before the washer pushes out.. any help much appreciated! I'm on a 2008 wr250 if that helps.

Thanks in advance

Myles
 
I'm not sure what's going on there. It might help to have all traces of gas/oil mix removed from the o-ring and its seating areas--it might be lubricated to the point that it's too slippery to stay put under force. If that doesn't work, inspect the seating area for the o-ring carefully--any damage there? If all looks good, then it might be worth just trying a new o-ring.
 
I've been trying to find a replacement one but nothing in the UK it seems. Where do you get yours from?. I'm happy to go universal with a replacement one. Was surprised how basic the set up was.. cheap plastic thread formed from the tank that the petcock screws on to. Was expecting a filter type petcock but mine just has a little straw tube.. Will post a picture in a minute as someone might say I've not got the right o ring or even petcock.
 
Here is what was happening to the o ring. Have dried it of and tried again and appears better seated20131219_170559.jpg20131219_171120.jpg

Here is the petcock and o ring... does this look normal to everyone? I noticed the screws were already a bit chewed so I suspect the last owner had a similar leak issue. Possibly of home made repair so always good to get some expert advise!

in picture 3 look at the threads inside the petcock at the tube, there should be a screen that's shaped like a tube
I bought mine at my local dealer OEM part
 
Thanks.. I wondered whether something was missing as all the photos I've seen have a kind of filter looking thing which I guess the straw tube goes in.. off to my local dealer tomorrow.. hopefully they are still accepting that the WR exists rather than the all new ktm/husqvarna range!

Thanks again for your help/advice
 
Update - bit of drying out of the o ring and using a flat head screwdriver to hold the o ring in place and bingo, dry petcock.. need to ride it and make sure it holds but so far so good. Cheers for all the advise.
 
It may be that the oring isn't the correct one. It looks a little fat to me.:excuseme:
Hylomar gasket sealer works good for holding o rings in place and is completely fuel resistant.
