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 The previous version was outdated and no longer supported.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

hey fellas. i run the standard 10-60 fully synthetic in my 610 and as we know the oil is red in colour. after a few hundred miles the oil goes a dark red/brown and i've been told that this could be because the piston rings are wearing and carbon is getting in to the oil. is this nonsense? the bike's got just over 10,000 miles on it now and i change the oil + filter every 1000-1500miles.

toying with getting it taken apart and checked out and then while they're at it doing the big bore kit & high comp piston.

cheers :)
 
If it's got a wet clutch, the oil WILL get dark...

What brand oil?

The 10w50 Castrol RS racing syn I run in my 630 is gold going in and black/gray coming out, and I get about 2000 miles on it before I start feeling it in the shifts.
 
The litmus test for bad rings is a compression test. If it's got good compression I would not worry about it if the oil is darker in colour. Now if it goes darker in color, that is a different matter. In that case, I would sell it and buy a new bike immediately. :D
 
cheers chaps. i would say from the general pull of the motor it's got good compression still. i'm using motul 7100. this is the first bike i've used fully synth with. with my previous bikes the oil always came out black and was never an issue. it's just something someone said to me that got me curious.
 
I would recommend the Motul 5100 semi syn. You do not need the expense of the 7100 fully syn imho. The 610/630 are not really pushed too hard and a semi can if fact be a little better for this type of motor.
 
If lubricating oil in a recirculating system doesn't get dark, it's not performing its primary function, to carry dirt away in suspension.
