Just dug out of my garage and cleaned after 20 years. Also now registered on its original plate. Only problem is the standard unleaded petrol is making the fibreglass tank go sticky inside. Anyone know if Shell premium without ethanol stops this or has anybody tried the Aspen alkaline petrol in motorbikes. They sell it at our lawnmower shop either for 4 strokes or pre mixed 50:1. Only snag £18 for 5 litres. I'm not sure whether to line the tank and I've heard about people having nightmares with the coating failing. Someone also said to try and get hold of aviation fuel but I've no idea who'll sell that to me?
