Recommended Predelivery Engine Break‑in Procedure
NOTE: Do not use premixed gas and oil in this engine. Use straight gasoline during break‑in and after engine break‑in.
The recommended predelivery engine break‑in procedure for the sport jet engine is important to ensure proper performance and
maximum life from the engine. The following break‑in procedure allows the pistons to ease into conformance with the cylinder
bore.
The engine automatically receives extra oil during the first hours of operation. This extra oil mode will complete in about ten hours.
