Thanks for the add. I recently purchased my second Streetglide. it is a 2018. I have only put 115 miles on it since the weather has turned to crap. When I start it it blows some blue smoke then quickly disappears. My 2015 never did it. Just curious if anybody else had this problem with the M8? I have seen a video by a machinist that says he is seeing M8 heads come in with misaligned valve seats.
