How would everyone reccomend to clean out the fuel tank i look in there and i can see dirt all through the petrol
Take the tank off and then take the tap off to drain. Give a slosh around with fuel or solvent to get rid off any bits. Are you sure it's dirt? It's most likely corrosion. You can buy fuel tank 'kits' to restore it.
As Jim says ...tank off , fuel tap/petcock off , cap off ..... discard the fuel and take a good look inside Have a look here ..... http://2fiftycc.com/index.php?threads/petrol-tank-sealing-kits.1455/#post-9739
