Just Bob +1 on that. When I got my bike I noticed that at low RPMS and around a steady 35 mph or so the bike had a slight surge. When I took it in for the first service that is exactly what they did and it solved the problem. Still running stock cans and jetting (hoping to get some Wings this summer) and the bike has been a champ. I did de-sas it but was too lazy to remove the rear cannister in the tail.
