Break-in

The first 1,000 miles are the break-in period. Use conventional oil only, change the oil and filter at 500 miles, vary your RPM, and avoid towing, heavy loads and long idling. Check your oil level regularly, since some oil burn-off is normal until the rings seat. Following the break-in procedure is required to keep your warranty.

Warranty and core

Warranty: 1-year unlimited-mile warranty on the engine only; labor is not covered. Optional 3-year extended warranty available for $1,500 (includes labor coverage at $50/hr). See our Warranty & Refund Policy. Add the 3-year extended warranty to your order.

Core charge: none. All engines are built to order.
