Hi everyone, I thought I at last solved my problems with a smoky bike using Lucas W50 full synthetic, it seemed not smoking so badly except in very poor condition like long que and higher air temp.
Good things often won't last, so that Lucas oil seems not to be imported in the whole Europe since some months ago.
It's quite difficult to find SAEw50 full synthetic, so I ask if a SAE50 mineral can work with our hot engine bikes...
Thanks anybody for any advice.

From what I understand, Mobil 1 Racing 4T 15W-50 is recommended for Harleys in Europe. Not sure if you have access to that.
No expert.........but all recommendations show to use a synthetic, not mineral.
Per the Service in on this website" The company recommends a fully synthetic 20-50w oil, designed for motorcycles. It is mperative to purchase ONLY motorcycle oil for the needed clutch additives."
Nobody had answered yet so just thought I would give it a quick response. The word "recommend" does not mean it would not work.
