  • 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 The previous version was outdated and no longer supported.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 Oil in airbox

Since I installed a Keihin in '09 WR300 I notice there's a fair amount of oil pooled in the bottom of the airbox whenever i clean filter. Definitely not filter oil - use water soluble stuff. Looks & smells like 2stroke oil. Don't know how it gets there,but when I brake into a corner then try to accelerate after cruising in top gear a while ,it almost dies & takes a few seconds to clear again.I believe the oil is running down into carbi.
The jetting is nice & crisp- 172M,JD red needle/middle clip,48PJ, 1-1/2 turns a/s. I set the float lower too without any effect.
I'm completely puzzled, any ideas?
 
It's just premix oil. It's normal. All of my 2 strokes do it. I just wipe it out whenever I change the air filter. I doubt it effects how the bike runs.

+1 on the premix oil. My 2010 WR300 does the same thing and no running problems at all.
 
Thanks for replies. So fuel must blow back in the airbox,evaporate & leave oil? Theres quite a bit of oil in there,enough to run into the carb under braking.Its the only explanation I can think for the massive bogging thats happening sometimes. The jettings spot on,tried diff plugs,lowered the float & run at 40:1.
Should clarify,oil is pooling in the boot between filter & carb.
 
Run your bike for a moment some time without the aircleaner boot attached to the carb. When you rev it up, you'll see a fine spray of premix, almost like a thin cloud come out of the back of the carburetor.
