Ready for comical levels of bad, even by Chinabike standards this thing is so bad it makes our bikes look like a Rolls Royce.
So, let's start with the 3 dimensionally warped exhaust flange. They got this sucker so hot, even if I wanted to try and straighten it, I don't think it would hold a seal without grinding half of the flange away. Then it would be super thin. Thankfully, they did open a warranty claim for it so I should get a new one.
THEN! To skip forward, I noticed the engine would get tight and loose as I turned it over. The crank is so out of true the bevel gear (small drive grear on the crank) is visibly moving in an eccentric manner. I had planned to pull the crank and true it anyway because I always planned to balance it. Not only that, but everything has a gritty feel to it like it was rolled in sand. Even the crank and lower rod bearing sound SUPER gritty.
Imagine my surprise when I split the case and THIS fell out. (picture is linked, larger image for better detail if clicked ) This isn't even all of it lol. Everything is coated in aluminum flakes too. I have some work ahead of me
So, yeah.... New breaings going in for sure.
