  • 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 The previous version was outdated and no longer supported.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 Awesome New test Track, Plug pics; On the edge?

Pro Class
Rediscovered a friend's woods moto track. They put a lot of work into this. It over 3/4's of a mile thru the woods and we will be spending lots of summer time here. These clips are from before I got to the better sections and ran out of battery. I have to get a better video camera and start putting some things together. Anyway, the plug pics compare a new plug and the one after this test session. The riding in the videos is about how it went for 2 hours or so. So the plug read is mostly from the main.
For the ride...with the '09 WR125, CR ignition, FMF Fatty pipe, stock silencer
460 Main, 37.5 Pilot, 6-chy-16 Needle - 3rd clip down, #5 slide, 40:1 Klotz R50

I think I need to bump to the 470 main and adjust the clip. My old fashion views are that this is too lean, but my moto buddies like the look of the plug. I know you can't see down in the plug, but the base is dark.

Opinions? On the plug (and the track!)

We are heading out to the PA round of the GNCC on Sunday. I don't think it will be this open, maybe a lot of rock trails.

The track was the teaser...I knew you'd like that. It is the perfect place to run at race pace.

But, what about the plug?
 
TOO LEAN****************************************************************************************************************************************************************!!

that thing needs to be brown. go up one, maybe two on the main and do a main jet verification test as ive described in other threads....pay attn to the porcelain only.

warm it up and get it cleaned out as much as practical.
install a new plug in a warmed up engine.
start the bike and jump on, go WFO in first, second and at least third gear....then, pull in the clutch, chop the gas, hit the kill switch all at once. do not let it idle. then, read the plug. dark brown? we are safe for now and ready to go to the next circuit. if it is lighter than that, it's lean. black and oily? go down one size and redo w/ a new plug.
always do main jet verification with a new plug
