Shame about the F2. I'm a big fan of the 600Fs. Mine's a 1986 Ninja 900. My first step: make sure the crank turns. :-( I drained the tank before storing it so the carbs shouldn't have gummed. But I'm sure that after 25 years of immobility its road to resurrection will be full of potholes, irregardless.
It's been sitting for 25 years... during which I bought two more bikes, a 2004 Yamaha FZ1 and a 2015 Ducati Diavel. Don't ask me why. Apparently owning an excess of bikes is my penance for... some past sin.
