  • 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 The previous version was outdated and no longer supported.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 Spark plugs: differences

Hi, anyone have any thoughts on Spark plugs for the WR125? Stock is a B9EG (I believe), would a B8EG hurt, help, or be hazardous for the motor?

Just to confirm, B8EG is a hotter plug, right?

thanks,
JS
 
The 8 is hotter, with NGK the higher the number, the cooler it is.
If you run the bike hard, high rpm, the 9 is better. If your wife is lugging around, the 8 may be better. Depends also on your jetting, just keep a watch on plug color, and it will tell you which way to go.
I am currently running an 8 in tight single track, but that might change as I get the PWK the way I want it.

Thanks. I fouled the first plug with the bike last weekend following my father-in-law around at walking pace for about an hour in 80 degree weather. The only plug I had was an 8 from my 250 (not the BR8EG, but B8EG), and the bike seemed much happier. It would not load up as much, until I was able to put a smaller pilot jet back in at the truck.

Why would you not want the hotter plug when riding full throttle?

It can burn a hole in your piston in a worst case scenario.

The 'R' designation only means its a resistor type plug so it wont cause radio interference. I'm pretty sure the Husky spark plug boots are also resistor type, so no need for an 'R' plug. Although it wont hurt anything to use one and they are more readily available.
