Such as;
Those tiny phillips screws on square brake fluid reservoirs, that are made of chocolate and round off before you even insert the correct size screw driver.
Or removing the airbox from an 06/07 ZX10, which requires turning sideways, the muttering of a secret phrase, a diagonal tug to the left, three scraped knuckles and a final rotation along the y axis.
Or perhaps the many handed job of refitting a rear wheel while holding the brake caliper in place, holding the spacer on both ends of the axel, lifting the wheel, lining up the holes in the swingarm and pushing the axel through.
Or warning of those shinny chrome nuts and bolts that are in fact plated and the plating flakes off the first time a spanner or socket is attached to the nut or bolt.
