Kind off reminds me of the time I went to the Dutch Bike GP - in the camping area, every night around midnight, about 20 guys would start up these extremely noisy V12engines.
These crazy guys had towed V12 jag engines from all over Europe on there own little trailers but, there was only the engine & a saddle on top of the motor.
So theses guys would sit on top the motor & use a piece of string to operate the throttle & red line the things through straight pipes
I tell you mate when one of those things start up at midnight the whole campsite wakes up!!!
