That's good, some sort of time machine at work

BMW might mention type approval in their reasoning for not sanctioning this but they'd be wrong. A UK type approval is for a new vehicle. You need type approval before you can sell a bike as new. Once sold, any modification away from the approved spec is a matter between the police, VOSA, the owner and eventually a courts interpretation of construction and use law. I can't concieve any argument that would make a spigot in the intake a legal matter in the UK. This differs from say Germany where the TUV approval applies for the life of the vehicle and must be maintained by only using approved parts. Here the offence is not that you did something dangerous but that you failed to get it checked by the third party. What BMW would really be saying in most juristictions is that if you modify their part they won't take any responsibility.

Their attitude to warranty claims added to a "modified" bike could well be worth thinking about. If the spigot breaks off and goes in the intake, fair enough, no warranty on the engine. Would BMW pay out if the forks snapped though?

OT, What BMW (and others) would dearly like of course is a Super-TUV where the type approval stated every single part, by their part number and that's all you could legally fit. Can you imagine the price of a headlight bulb if it had to have a logo printed on it?
