  • 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 The previous version was outdated and no longer supported.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 Base gasket thickness & performance

My friendly dealer advised the the two easiest ways to gain performance on my WR250 was an aftermarket pipe (FMF Gnarly... check) and to put a thin gasket in where the cylinder meets the case. My gasket from the factory appears to be .015 or less so I doubt if there is anything to gain for me but I was wondering if anyone else's WR250-300 came with a thicker gasket. My 250 has more power than my skills can use but I thought others might want to know this.
 
Alters the exhaust port timing slightly and compression - thinner more low/mid and thicker mid/top.

If you had to to want to go lower than you really need to calculate your squish area and get the head skimmed...then you have to readjust the exhaust timing depending on how far or much you have skimmed the head.

l've never done it but a few racer mates have blueprinted their 2t engines just to the the middle of a manufacturers tolerances and the smoothness and reponse is pretty bloody good.
 
I hab RB Designs set my squish when my bike was new(08 wr 250).Now I will use different base gaskets to keep the squish correct when doing a fresh top end in case of any variables with the piston.
 
Buy the race head - cheap as chips, and gives a big boost to bottom end and mid range. Takes only 30 minutes to fit and increased the compression on mine from approx 155 to 185 psi.
