Hum, I have the chance to live "up the hill" (110M msl) and when I want to get out of here the short way I have to descend quite steep.
I have noticed that with my Funduro 650 1996 single it did pop from time to time, while descending... until I had the spark-plugs changed ! After that no more popping!
The F8 2008 is not popping at all.
Must be something with the gestion of the engine mixture, spark-plugs, can etc...
But if you enjoy the sound that it does when popping, good for you
If my 1200 GSA ever stops popping and banging, I would have to get rid! I had a Ducati 748 SPS that could throw flames out of the cans, It sounded awsome!
mine used to pop and fart beautifully ..... until BMW put a revised fuelling map on the ECU which changed the whole character of the engine, and also took away a lot of engine braking ... I wasn't a happy bunny, and when I complained they said they couldn;t roll back the changes ...
