Engine casing cracks?

[Admangia]

Even if this particular flaw is not likely to fail it is not of no concern. They clearly had issues with that casting. Was it temperature, inclusions in the metal, both? Are there other areas that are unseen that are flawed. I would show it to the dealer. He will not do anything about it but if it fails two months past warranty it is documented that it was an issue that the dealer ignored. They are not giving these bikes away and that kind of subpar component should never have been let out the door.

Gentlemen/Admangia, not a flaw, not a defect. Looked on my own CT in the exact same spot and it also bears an inconsistency compared to the surrounding surfaces. Mine's a rough, lumpy joint line with the same diagonal-direction feature and in the same location, but with small rises and recesses instead of a constant recess. It's most likely either a joint from a mold insert/seam, or some parting line where the wax (plastic) or sacrificial molding matrix butts to the adjacent one there. Not to worry; the thickness of the aluminum in the region is huge compared to the depth of that recess. If you were to measure the recess ("crack") it would probably be on the order of 1/2mm IME.

Thank you for clarifying. A prior post added that I might mention to dealer and will do so when I stop in next time. It is otherwise performing flawlessly and impressed as it took me through a good deal of challenging terrain over past couple months!
TY,

Agree. Mine looks exactly like that.

I guess that is reassuring. Going to mention to dealer while under warranty per post recommendations TY,
