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 The previous version was outdated and no longer supported.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

Does anyone know what the maximum advance you should see with the JD ignition unit in race mode is?

I have one that I need to set the timing on, but I'm not sure what the what the maximum advance is programed for. If I could get a hold of the cable and software I could check it, but I can't seem to get that either.

I know the stock CDI unit runs about 26 degrees of advance, but I'm not sure how far JD pushes it.

Is this for your WR250?
 
Yes. I put it on back in the spring and found that the timing was way off, but I had a race that weekend and didn't have time to sort it out, so I just pulled it back off and never got back around to trying it again. I figure I'm going to have a little down time here soon and need to try and get it set up right.

I knew something was wrong as soon as I fired the bike up and took it for a spin. This set up normally give good results and it was running like a pig. So I checked the timing with a light and found I had no advance just above idle and it went negative after that.

This is with a '01 stator. With the '02 unit it's a straight up affair and runs great, but I've never had a light on one, so I don't know for sure what the max. advance was. Something I should have checked for future knowledge, but never got around to. :banghead:
 
OK, I've got it figured out now. it's the difference in the "trigger" on the '01 vs. '02 flywheel.
