id call up the manufacturer and ask them. That way if they say yes and it shits the bed they are at fault. Get that in writing though..
That looks like its just a wax from the wire coating. I dont think it would be an issue but it could be. Definitely doesnt look like an oem stator.
It should be. Came with yamaha box and bought from ronayers.
I emailed them, they said that most will have some extra glue or flaking from manufacturing molds and that I can just clean it and install it.
what do you think?
