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 The previous version was outdated and no longer supported.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

Has anyone ever done this on a 2 stroke. I pulled the head off my 300 to mill it and noticed that the plug protrudes into the head by about 1/2 a thread. That got me looking at the electrode vs exhaust port relationship. I wonder if it would make any difference if it was aligned. Cam
 
Research tells me that the open part of the electrode gap should face the exhaust port. I will try that. Mostly done by shiftercart racers. Cam.
 
Yea there may be something to the theory but unless you tune your bike so finely you need data logging on egt every time you ride it then you should prolly just settle down
 
When I modded the head on my new 2018 150, I re-installed the chamber insert so that the open end of the gap was toward the intake (guessing that the transfers "shoot" toward the center from the sides). Felt like a stock motor with a good head mod, to me. But it's certainly not gonna hurt. I think indexing is more of an issue on high end 4 strokes and race car engines, when valve location affects cylinder filling and charge density at different locations within the chamber.
 
I was reading some outboard motor info and often the fi motors runability issues were solved by a service bulletin to index the plugs so the bent part was facing the injector. Not our bikes but got me thinking. Too cold to ride. Cam
