ZX6 Wishbone issue

[ChrisCorbett]

Building my ZX6 and haven't got far before discovering an issue (my error I am sure!). It tells you to use B and D inserts for the suspension hangers on front and rear of car and as I starting off with stock build I did as I was told!
Problem is wishbones are stiff on the hinge pins I guess due to the angle of them. I always aim to build any car with wishbones that are completely free and fall under their own weight whereas these don't! Will they free up over time or have I done something wrong?
