Important Notes
- Mounts are designed to fit Felt-Faker style frames
(may fit others as well) - All engines are shipped with large squish (1.0-1.4mm) to ensure safety when first tuning. You may adjust squish for increased power but be aware this will cause extra wear and tear on the bottom end. DO NOT go below 0.8mm squish.
