GoPro: Motorcyclist Attempts To Cross A Flash Flood

ha!

Anyone who watched this on Ch4 last night will have seen  plenty a flooded engine:

Hydroplaning Bike | Speed with Guy Martin | Channel 4

That was very surprising how they pumped out the water and way to go, it had just been 30 metres deep :eek

i was quite surprised at that too, thought there would have been a bent valve or two at least. they did change all the oil etc too of course and blow the air out the filter as well, i just dont think it showed all that each time.

I expected there to be internal damage to the motor due to hydraulic lock too, especially a 4 stroke being dunked in the water with the throttle wide open.  Two strokes are a bit more forgiving.  A mate used to run a jetski centre where his hire skis often had to be recovered from the bottom of the lake.  Take the plug out, squirt a bit of duck oil down the plughole, spin it over a few times, stick the plug back in and they would fire up straight away.

Fair play to Guy though, he stuck with it but I bet his leathers felt horrible when soaking wet, I'd at least have expected him to be wearing a wetsuit underneath.

and if you didn't see it, it's being repeated on Channel 4 in a minute......
