And dont be afriaid to have them show you where this recall issue is and how it is checked... I would stand there and watch them !!! If the Service Manager is a stand up guy and a rider...he should support your wishes.
I don' twant to sound like the dome's day messenger, but it you your life on that bike...you got to have confidence in your equipment and your skill. If I didn't I would dump it like a " cheating wife"

...and never look back!!
I do hope it is just a noisy sensor !!!

..
Good Luck,
