What can fail
The heated grip on the right handlebar can expand too much when turned on, pushing against the throttle mechanism and preventing the return spring from working properly, making it hard to slow or stop the motorcycle.
What the fix does
A spacer will be installed to create enough clearance so the heated grip can expand safely without interfering with the throttle mechanism.
