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 The previous version was outdated and no longer supported.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

450 smr engine grinding

Hi guys

My 450 smr was running perfectly and all of a sudden I have a heavy grinding sound coming from the motor. I drained the oil and on magnetic sump plug I had the usual small fillings.

The motor atill pulls very strong and no funny sounds other than the fact it sounds like its grinding big time.

Anyone have any idea what is wrong?

Thanks in advance.
 
check location of noise, can be the breather cyclonic disc on the end of the cam shaft when it comes loose and the hole gets out of round the thing makes an ugly but relatively harmless noise. It can also be the auto decomp cam assy. But thats all up on top.
 
Start it up and use a long skinny screwdriver mashed into your ear and put the tip on various spots on the motor: top end, head, cylinder, lower end engine cases, etc. You might be able to narrow down the search, Like Robert said, easiest stuff would be right under the valve cover.
