# Amsoil Synthetic V-Twin Primary Fluid (946ml)

# Lock in Torque. Eliminate Slip.

Amsoil Synthetic V-Twin Primary Fluid is a purpose-built lubricant designed to ensure solid clutch engagement and superior cooling for the primary chaincase of Harley-Davidson motorcycles.

The "Primary" is where the power leaves the engine. It houses your clutch, your primary chain, and often your stator (alternator). Using standard motor oil here is a mistake—it contains friction modifiers that cause the clutch to slip under hard acceleration. Amsoil Primary Fluid is engineered with a balanced friction coefficient. It grips the clutch plates firmly for instant acceleration while dissipating the extreme heat generated by the stator in Pakistani summers.

Consistent Clutch Feel Formulated without friction modifiers. It ensures "positive engagement," meaning when you release the lever, the bike moves instantly without the mushy feeling of slipping plates.

Cools the Stator The electrical stator lives inside the primary case and gets incredibly hot. This synthetic fluid transfers heat away efficiently, preventing stator burnout (a common issue in older Harleys).

Chain Protection The primary chain spins at high RPMs. This fluid creates a thick, durable film that cushions the chain and the compensator sprocket, reducing mechanical noise.

Prevents "Drag" While it grips hard, it also allows for clean separation. This prevents the clutch from dragging when you pull the lever in, making it easier to find Neutral at a stop.
