Thanks to gsr1300rguy / crazy bill / godzuki31 /oddball for replies...(my busa flopped over, still can't work out how or why). Wallet is much lighter now, the replacement fairing panel cost me £280 (UK). Something else bothering me - although it all happened so quickly, I remember the engine had stopped when the bike was on its side. Is there a built-in auto cut out, because if not, a sudden engine stop may have been the cause. If so, has this happened to anyone else? Engine was difficult to re-start afterwards.
