Hi Eric! Was it the left cylinder that smoked? You probably already know this stuff but please keep an eye on the oil level, so it doesn't get too low. And when you start the cold engine, watch for smoke from the exhaust.Hello, Erik from France. Just got My R18 on Saturday. Went for a ride on Sunday. Just had the exact same problem after about 20 miles... Decided to let it run and it completely disappeared after 2 or 3 miles. we've done about 100 miles after this "episode", nothing happened... I will let BMW know about it and I Will keep you posted... Erik
