This video shows an operational cutaway of a BMW S1000RR — a 193HP superbike — bumping against its 14,200RPM redline. A cam and valvetrain at 236 cycles per second is an amazing sight (and sound).

Hi guys. 

Do you think that this video shows smoke or is this just oil being beat into the air? 

Note the vavle rotation and camera ailiasing (wagon wheel effect).
