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 The previous version was outdated and no longer supported.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

[EFI] SMR 510 VS 450 ENGINE/MOTOR?

Are these engine blocks/cases identical in a 450 SMR and a 510 SMR?
Would I be able to fit a 510 SMR crankshaft etc. into a 450 case?
What are the differences in the bottom-end?

OEM part numbers match

I don't know (rancher1?) but it sounds like you answered your own question.

So "yes".

Reason why I'm asking is because my bike locked up yesterday and cracked the case. Have no idea why. Top-end was rebuilt 60h ago, changed the oil every 20h (streetriding), valves checked 40h ago. When I swapped the piston, the crank had no freeplay or signs of wear like everything else in the motor. The crack is behind the stator cover on the left, inside is what I assume to be the bearing for the counterballancer. Starting to make me wonder if the huskies are even reliable:excuseme:

That fracture looks like the force was axially along the shaft supported by bearing #8. The bearing retainer screws #4 may have been hit or pushed to the left by something impacting the counterbalancer shaft? IOW, on the other side of the engine.

If your engine is okay (unlikely), you may be able to just get rid of the CB and patch things up. But really, you probably need more than just new cases.

I'm not a big block expert by any means- but my opinion through observation is that these engines are very reliable.

good luck (was it juice mushroom?).

Yes it's me. The cases are just a start and found them cheap. Going to need all bearings, connecting rod, piston etc. but if the crankshaft is toast, my bank account will be also. I have the entire winter to figure it out.
Thought the huskies were as reliable as KTM's RFS engines if not more reliable. Might also post a thread with pictures when I take it apart, feel like fellow husky owners might want to see the carnage.
