He obviously wasn't riding a bike fitted with a shift kit and he was riding whilst intoxicated.
Shift kit's work terrifically well, that is if the person has a basic understanding of mechanical systems and a basic level of competency.
Lets face it, more than one person has died falling over drunk and the medical establishment kills thousands of people each year through the administration of incorrect medicine/treatments, and in amongst the noise of daily life you hear of a single case of someone being killed on a China Girl - with that in mind i'm not throwing my hands in the air and running around the room in mad panic like the world is going to end on the simple basis that i've installed a China Girl engine in my bike, and without any personal injury for the last 40,000 kilometers.
