Hi- I want to perform a piston soak with your fuel injector and carb cleaner part no #0116. Do you have a procedure / instructions for that? After the piston soak, do I need to add some type of lubricant through the spark plug holes? This will be done on a 1983 Honda Nighthawk 650 air-cooled motorcycle. Thanks, Aaron
Berryman B-12 Fuel Injector Cleaner (part #0116) is very effective in removing hard carbon by way of a piston soak. That is accomplished by pulling the spark plugs, putting 0116 in each cylinder, letting the product dissolve the carbon, and then removing the mixture from each cylinder. You will not need to follow the procedure with a lubricant.
