Removed the bodywork and cleaned the outside of the tank in preparation of a tank cleaning procedure to remove rust, there's a lot of rust inside and from reading around the forums this is what I'm going to do, please advise:
1- pressurize the tank with an air compressor to remove the remaining bit of fuel in the tank and push it out through the petcock.
2- put the petcock in off position, fill the tank with 2 gallons of white vinegar, 2 pounds of salt and the rest with tab water till it fills to the top and leave this for 3 or 4 days.
3- Siphon all out and rinse, fill again with water and baking powder for half an hour, and scrub a bit using a bottle brush.
4- Siphon out all and fill with fuel and a quart of 2 stroke oil and leave for 1 day.
5- Siphon out and fill with regular gas.
6- New fuel lines and new inline fuel filter to the fuel pump.
Should this be enough for the fuel system?
For steps 3,4 and 5, should I use the air pressure method to force the liquids out through the petcock instead of siphoning out? this way I can clean inside the metal hose that runs from the bottom of tank to the petcock.
For the carbs, I'm just gong to clean the air filter and pour in some carb cleaner and see how it goes.
Once I get confirmation on this from you guys, I'll start this process, and in the meantime will remove the radiator and and change the timing belts.
