  • 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 The previous version was outdated and no longer supported.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 Spark plug confusion, B8EG or BR8EG?

2012 WR300:

Checked a couple of the workshop manual PDFs now, and they all say BR8EG in the general specifications, but further down in the manual they all say B8EG.

What would be the best one to go with? B8EG is likely better but will it damage CDI or something in the long run?
 
Use the resistor style of plug. You will probably get poor and rough engine performance out of the B8EG.
 
I tried the non resistor B7ES in my WR300 and the engine ran well but I had problems with my Trailtech speedometer resetting and doing funny things because of the induced RF interference, I then changed back to the BR7ES and and problems solved.
I did not notice any difference regarding the engine.

Thanks. Engine runs fine, even with B8ES instead of B8EG. But as long as I know people runt the resistor plugs without having issues with cold starts, poor performance/weak spark etc, it's definitely the way to go.

Thanks for the input! Did you have issues with fouling spark plugs when using 8s, or why did you decide to go with 7s?
 
For my riding style (slow / low RPM enduro) I got better spark plug electrode color with the 7 grade. I had some fouling with the 8's before when the jetting was a little off, later the jetting was spot on but I never decided to go back to the 8 and never had an issue about it ...

If your riding style is more WFO I would probably not do that ...
