Hey, I'm new to airheads. Have had my eye on 75/5's for a couple of years and gearing up to buy one. It'll be a rider as I'm some ways out from my own Barber. Been trying to find a check list of pre purchase items with no luck - wondering what resources you gents might point me at. What should I ask the seller? Things I should look at when face to face with the bike? Stuff like - carbs, valves (isn't there something about pre-unleaded petrol?) tank work, hell - even knowing it's not a Frankenstein! Any good books out there? Many thanks.
