‘Pafo’ is doctor’s shorthand for ‘Pissed and fell over.’ ‘Picnic’ is computer nerd’s slang for ‘Problem in Chair, not in Computer’. Pisnib? Problem In Saddle, Not In Bike. Some years ago I set out, heavily laden with luggage, on a longish journey on my Velocette Venom. I’d hardly gone five miles when the bike seemed to run out of petrol, so I reached down and opened the other fuel tap. No go. I shook the bike from side to side and heard plenty of fuel sloshing around in the tank. Then I delved for a plug spanner and checked the spark – yes. Now in my not very long book spark + fuel = engine runs. So I kicked the engine over and away I went.
A few miles later it happened again. This time I didn’t bother getting the plug spanner out, I just waited a few minutes and set off again. It was a hot day; could the engine be overheating, causing magneto failure? I hoped not.
When it happened again after another five miles I happened to be on a very quiet stretch of road, and I noticed a gentle hissing sound. Oh, no; not a puncture too? The hissing subsided but the tyres seemed fine, so off I went again.
And it happened again. This time I simply sat on the roadside bank, lit a cigarette, and had a think. (It is not yet as widely realized as it should be what a disastrous effect the current disapproval of smoking is going to have on Man’s inventive capacities.) There was that hissing again. I prodded the tank bag. The hissing stopped. I re-arranged the tank bag so that it no longer covered the little hole in the fuel cap. Problem solved.
This is actually someone else's Velocette Venom; I can't find any pictures of the one I used to have.
