2014 GSW..my tpms has always activated quickly as I started riding. I now have a Cymark tool kit where my rear (plastic frame) pillion seat was. I’ve noticed that my tpms signal does not come on until I have ridden a few Kms. Coincidence??? My rear will lose signal occasionally but usually comes back on later (suspect battery in rear is going weak). Could my metal Cymark toolbox be disrupting my tpms signal?
