I have a small fuel leak on my SP3. It's coming from one of two plastic tubes on the left (gear change) side of the engine - they disappear up into the region of the fuel tank. TBH I don't remember seeing these tubes before the bike was serviced recently. The leak is slow ATM - about one drip every 15 seconds - but it's near the exhaust... I'm guessing that the pipe is an overflow or similar for the tank, but I'd appreciate some advice before looking under the tank - sod's law means that the tank is full to the brim, which is 20 litres of so. Thanks in advance Andrew
