Hello, dear Guzzi friends, allow me a question about the Cali 1100 Vintage. Mine is Bj 2006. When setting the valves I did not find an “S” mark on the flywheel, but a yellow arrow. The “D” is like it is described in the beautiful video of Moto Schrauber. Is this variant available? Unfortunately, there is nothing in the workshop manual. Thank you for your help! Greetings Uli
