Default Propane Injection Exhaust

anyone ever inject propane into their exhaust for flamethrowers? im sure everyone will hate on the idea but im thinking about mounting a 16oz bottle in each bag on the streetglide.

why not? just make sure your exhaust sticks out a long way, the flame comes back quite a bit when you shut it off... I'm an old hot rodder & love flame throwers (on other people's cars), but am used to the old manual choke model t coil way. It's so simple now - you can buy a kit from Amazon:
Amazon.com: Hot Licks Dual Exhaust Flamethrower Kit for Automobiles or Motorcycles: Automotive Amazon.com: Hot Licks Dual Exhaust Flamethrower Kit for Automobiles or Motorcycles: Automotive
edit - not a propane kit but simple enough if you have a choke
edit again - they sell plans for gasoline injection - could probably be adapted to propane

I can see this idea coming in as first place either in a video for Americas Funniest Home Videos or a first place award spot on the Darwin Awards.
