Tuning Tips for Cycle Rama Cams: Cycle Rama cams necessitate tuning by a skilled Dyno Tuner. Ignition timing must be adjusted and modified to maximize performance. Without proper tuning, you won’t achieve maximum performance. Proper tuning requires the Dyno tuner to determine the ideal air/fuel ratio and ignition advance for your motorcycle. Relying on auto-tuning to detect detonation will result in low ignition advance and sluggish performance.
