I have noticed the same thing in mine, not as bad as that but some red showing at top of cylinder. I just chalked it up to starting it up in trailer and moving it into garage and shutting it down without it getting up to temperature. Lots of moisture in there from heat cycles in the enclosed trailer. :noidea:

LOL do they even recognize problems anymore? There so far in first they just love sitting on top so they could care less about some of us having issues!

Not trying to defend brp here, but I think that's the point of the new coating process.
The porosity helps retain oil and reduce wear kind of like an oil lite bushing does.
I do agree that it doesn't look good tho

From the pics, Like a very uneven coating if that’s what it is.
