  • 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 The previous version was outdated and no longer supported.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 Compression ratio check

So.. after nuking two pistons at 200. apiece I've decided to make more pre-assembly checks on my 93' 360. My owners manual calls for a squish band of .102", here's the page. Note the last paragraph before the specs.... lost in translation ?

does this mean a total of 1.1 mm (in my case a .6 and .5)

I also have a 2000 wr 360 workshop manual..
2000 comp.jpg
which calls for a squish band of .07". I've looked up the cylinders part numbers and they are different, also the compression ratio was raised from 6.9 1993 to 7.4 in 1998

anyone have specific knowledge on this ?
 
this is a common practice of modern bike engines
yes they did change the cylinder in 97, it was a port change to flatten the power band a bit, it added torque but the downside is stating it, the 93 kicks a LOT lighter than the 97 on, this was the reason for a decompressor that is discussed on Cafe Husky
to set the commpressed height is fairly simple, but their one page explanation is hard to follow for one thing it is an interpretation from another (Italian I guess) language and as such seems broken in our thought process
get a hold of me I will give you a hand if you want
fyi I live in Reno now, want to go riding when you are done?
 
I.'m all set up for the process but the info is misleading. Just figured out that in the newer compression check process they start with a.4mm base gasket and then measure for. 07"clearance which is where I went wrong last top end rebuild so what your saying 2premo is.... use .5 mm gasket and measure for. 102" clearance like it says in my manual. Not adding a second .5mm gasket additionally. Turns out .6mm base gets me .099" clearance good enough for the girls I go out with. Sorry for mixing metric and sae. and ya we should ride soon, lost your number PM me.
