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 The previous version was outdated and no longer supported.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

All 2st Fouled plug mystery

I'm looking for some help/advise. I have 2008 WR250 with about 100 hours on it. The bike has been bullet proof and awesome. About 4 months ago during the Atlanta summer heat and humidity, I fouled my 1st plug. I gave the carb air screw a 1/2 turn out and it ran great for 60 days. Now that the cool Fall weather is here, reset the carb and I've fouled 3 more plugs. Most of time they foul in the first five minutes but sometimes its after riding all day. The plugs don't look super wet. I'm due for a top end so could I be getting 'blow by' out of the crank? I just seams like more than a fuel mix issue?
 
Sounds like the same symptoms I had on my 125, I swapped every part of the electrical system and fuel system chasing it. Then put a new ring in it and no more issues. I went through 5 plugs in one 40 mile ride with the bike running great, the harder I rode it the faster they would foul. Still looking nearly new.

Later,
 
jmetteer - You're dead on. When I roll on the throttle hard under a heavy load and the bike is pulling a lot of torque is when I foul the plug. When I'm higher in the RPM and 'light' on the throttle, it rips... I was putting the top end off as a 'winter project' but it looks like I need to do it now.
 
Do a compression check and see for sure if thats the issue. Also check your coil and ignition grounds and makes sure they are clean and good. Spark plug caps can also be an issue on these huskys.
 
The guys at Halls said I was using the wrong plug. I have a NGK BR8es in it now. That's a resistor plug. They said to run the B8es (non-resistor). I'll try that for a few weeks...
 
I do run the non resistor plugs as well. Are you running the stock carb with stock jetting? My plugs were black with stock jetting. Currently I'm using the stock needle with the stock clip position, but I run 2-3 sizes smaller pilot and 1-3 sizes smaller main depending on the weather. No fouled plugs and no spooge.
