CW motorcycles replaced the fuel strip before COVID lockdown. I did ask them to use a float version instead of the strip but they said it wasn’t correct for the 2011 RT. I reluctantly agreed but after less than 1000 miles done since then I notice the reading is showing empty when it’s full. It can only be the fuel strip. I emailed CW but no reply. As they are no longer BMW dealers what do others suggest I do?
