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 The previous version was outdated and no longer supported.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

BMW S1000RR Valves at Full RPM

I was just waiting for my PC to blow up...:eek:

BMW S1000RR Valves at Full RPM

Watch the valve springs how they rotate up at the higher RPM.

13000 rpm divided by 4 = 3250 opening and closing per minute.

3250 divided by 60 sec. = 54.2 a sec

195,000 Opening and closing each second :eek: is that right?

Ummm is this a trick question??

3250 opening per minute would be 195,000 per hour, or 54.2 openings per second.

It's unbeleivable that the springs could maintain proper valve sealing & float the valves at those speeds:thumbsup:
 
I saw a nature show the other day and am sure that a hummingbird has 54 beats per second. I think you guys are confusing the new BMW with a bird. :D

Seriously tho, that bike is sick with the electronics being the highlight IMO, well electronics and 180 rwhp. Numereous modes for a riders safety just incase too much right hand twist happens. Rain modes, anti wheelie modes blah blah blah. All great stuff until you hop on a real (non electronic) bike, yard the throttle and it highsides you to the moon.
 
Awesome video:thumbsup:

And some people wonder why they have to change their oil so frequently. Its a wonder it lasts as long as it does. That oil has to beat to death.
 
Oil gets dirty from contamination.Clutch crap and piston blow by.Hence when you have a Diesel engine and have major blow by on every power stroke because of extreme cylinder pressure the oil has to be able to absorb the bad stuff[detergents] and the filter scrubs it.Go to Del West if you want to see how extreme valve train geometry is done.Twin cam boys take note
