Important Notes
- Pipes are made to be a "Universal" fit. Slight adjustments may be needed to fit your frame due to slight frame, engine, and pipe manufacturing variations.
- All engines are shipped with large squish (1.0-1.4mm) to ensure safety when first tuning. You may remove 1 of the 2 base gaskets to decrease 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.
- The carbs are tuned rich by default for engine safety. For optimal performance, the carbs must be tuned for your environment. 80-90 main jet range is expected, using Dellorto 5mm Round Jets.
