I had a DT1. Stupid me left the fuel tap on, and the bottom end of the motor filled with fuel over a week.
So I pulled the spark plug out, put it in first gear, opened the throttle and pushed the bike around the back yard. Started spraying stinky, stale fuel out of the plug hole - and because it was a DT1, the plug hole faces out to the left of the bike so fuel is spraying out like some sort of demented crop duster.
WHOOPH! Suddenly there's a five foot long flame belching out of the motor.
Well bugger me.
I want to move the bike away from the car its next to, so I keep pushing. Needless to say, I get another five foot long flame engulfing my arm and the left side of my chest.
So then I drop the bike and run to get the hose.
Of course, the hose is just a bit too short, and the water only just reaches the bike... Takes a long time to put the flames out, as fuel is trickling out of the exhaust pipe.
Didn't do any real damage to the bike - lots of black soot everywhere, and lots of mud sprayed up by the hose, but that's about all.
Ah, the folly of youth. Now, I'm a full eight hours older and much, much wiser....
I assume that my eyelashes, eyebrow and arm hair will grow back?
