Hello,

i have a fitting problem with my greys. the adaptor rings do not fit.
the inner diameter of the rings is 7,5 mm. and the diameter of the injectorpart the rings have to slide onto is 7,8 mm. so can you tell me whats wrong please? is it the wrong kit? i have it from burtonpower. or are there different grey injectors with different dimensions available? i have 0280150403, i think that should be correct. or is it an interference fit and the rings must be pressed on the injectors? can not believe that. 0,3 mm interference is way too much. i will destroy the injector when trying to force the rings on.
