kill switch backfire - how ?

[Enceladus]

being the responsible and considerate rider that i am (*cough cough*) i'd never attempt something like this, but.........
purely for knowledge purposes  how do you do it ?
also, any harm to the engine etc ?

ride along in a gear that's giving you highish revs then hit the kill switch. Keep the throttle open and a few seconds later reset the switch. Bang.

Only really works with carburettor engine bikes though as fuel injections systems shut down as soon as you kill the engine meaning no more fuel being pumped into the exhausted un-burnt.

No harm to the engine but it doesn't do the exhaust much good if you do it too often. Packing gets burnt and blown out.

Works best with the std can, get a nice flame too

Speak for your own can... my blue flame can looks and sounds like a howitzer firing!! I did, however, hear it can blow the exhaust valves into the piston. I've been cooling it recently!  :lol

It should also only really be performed when approaching a bus stop full of people.

Yup. Nearly missed the mini-roundabout ahead because I was looking behind and laughing so hard.

Mind you, I do feel bad about the old biddy that collapsed  :evil

on the subject of bus stops? around where I live they have transit engines in bustlers, so when I was driving my pick up I used to see a blind woman I know stood on the bus stop, and used to stop,  and yes she stood forward lol. didn't do it a lot but when I wanted cheering up. :evil
