The other day my mechanic had a BMW 650 with an oil leak to fix.
someone was checking the oil when cold and keeping on adding half a litre at a time, engine was overflowing with oil from the admission, all breathers, etc…, it’s a surprise it ran with more than twice the normal amount of oil in, turns out there was no leak, it was just blowing oil out.
Shame someone at a dealership does that, more so on a 30 grand bike.
