Suggested Break-in Method:

Static Running-in: Adjust the idle until the throttle is half opened. You want the tires to be in a status between turning and not turning. The opening throttle value is about 1mm width. Run the engine this way for about 250cc in rich tune condition. You can do a couple of heat cycles to accomplish this, heat --> Run a tank or two --> cool --> repeat. 
Motion Running-In: With throttle power between 50-80%, run the car in a figure “8” pattern continuously at low and medium speed for 2-4 tanks. Remember to check the engine after running out every tank of fuel. The engine temperature should by 195-230F. After the engine cools, loosen the glow plug 2 turns, then use the finger to turns the flywheel 360*, if the flywheel feels stuck or sticky at Top dead center, then repeat this action (Motion Running-In), then run another 1-2 tanks, then check once again. About 500cc on average and the break-in process is completed.
