Never owned one, but used to get a lift to college in one a few years back. Luckily I had a bottle of water in my bag and was able to put it out when it caught fire. Only the French would use paper to make the ducting around a hot air cooled engine. :shock:
The fire melted the plastic throttle cable outer, there was no metal under it, like a bicycle brake cable, so I had to jury-rig it to get us home. Never really considered owning one after that.
