Tuning Guide

• Lighter (4.0g–5.5g): quicker off-the-line acceleration and better hill climbing — best for heavier riders or stock motor setups
• Heavier (6.0g–8.0g): lower cruising RPM and higher top-end speed — best for lighter riders or big-bore builds
• Always install rollers dry — never grease a dry-roll CVT variator
