Put gas and clean, small rocks like driveway stone into the tank and shake for a while to git all the crap out, for the carbs the spray will work fine but ull need a toothbrush and verry small wire, then look up a diagram for that model carb and pull it
apart and clean the bowl out with spray and the toothbrush, and clean the jets out with the spray and wire, i have the same bike that i built into a bobber and have been working on harleys and japbikes for almost 7 years now
