Oh well, I have been reading this with a certain amount of interest and it finally got too much for me. I don't have a bee in my bonnet on this issue but I do agree there can be some quality control issues. Fortunatly mine have been fairly small and promply attended to.
To return to the issue of bonnets, ones with motors under them - not bees, I have never noticed any problems with fit from a visual point of view. Bear in mind that a gap of 15mm or so under the bottom edge is a design feature, not a fault.
I do, however have a point, where the RH bonnet curves over the scuttle, that the paint is rubbing despite the glued on material cushion. The other point that rubs is the centre fold down, at the hinge, rubs on the top of the aircleaner box. It has been given more clearance now but still touches on occasion.
