I want to remove the right radiator cowl on my 2016 Street Triple R to change the coolant. I have the Haynes manual and its pretty straight forward. The only problem is I can't get the two trim clips to release. I turn the plastic screw but the metal clip on the other side which the screw threads into isn't fixed and rotates at the same time. It can't be that complicated, what am I missing. Appreciate any help you can offer - thanks.
