many moons ago, a yam 650 twin, which i bought in about four boxes, i took them to my top floor flat, laid all the parts out on the living room floor to assemble it (like an mfi wardrobe) there was no seat, headlight and sidestand, managed to get these (apart from the sidestand) from the previous owner (after a good ol` rummage in his garage) put the bike together, then realised i could not get it out of the flat and down the stairs ! took off the wheels, bars and mudguards, and with the help of a couple of mates, got it out into the carpark, kicked it over and bang.....it started for two whole seconds then blew up ! never did get to ride it, sold it for £30 to a hippy....bout a year later, saw it parked outside a shop, painted purple and still with no sidestand, leaning up against a wall.......ahhh, the joys of biking !!
