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 The previous version was outdated and no longer supported.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

'06 SMR 510 Engine Rebuild

Well, It's time to rebuild the '06 SMR510, after almost 13,000 miles. About 2 yrs ago, the timing chain let loose and the intake valves hit the piston, bending one and breaking the cam bearing retainer yoke. I have since purchased an almost new head with valves, piston, rod, cam chain and tension guides. The plan is to send the crank and cams out for new rod and bearings, and change the main, crank bearings as well. My question is, assuming there is no play or crunchyness/ or they are not pitted, what other bearings should I change while I'm at it? Countershaft? Anything else I should look out for or do? I have never rebuilt one of these before. I'm looking for some advice, thanks.

Bike ran great until the little 2 cent bracket holding the cam chain guide rattled loose, compromising the timing. Man, am I going to locktite that thing back on! ;) I also found the clutch basket nut was finger tight! Prob locktite that as well!

The only other thing that ever went wrong with it was the stator winding bolts stripped out and wore my flywheel to the magnets! That happened when I first bought it, so It was covered. Seems like its always something stupid coming loose and wreaking havok on this thing! I think I'm going to just locktite everything for good measure! ;)
 
If that engine has a balance shaft I would change the bearing for it as well. i would just check the bearings for radial play and have a good look at the races and if good leave them alone. You could cause more problems by changing them. I would also inspect the oil pump gears carefully and make sure any oil sprayers are working and not plugged.
