I use this, their conventional oil and 80w140 trans fluid. Several Indy and HD mechanics have recommended this non synthetic fluid due to engine needle bearings. I do in my 114 and my previous 103 High Output. Oil debates are all over HD forums so make up your own mind about it.

This is the best primary chaincase lubricant. It provides clutch support when engine power has been increased.

Second purchase. Quiet in the primary. Most important the oil is compatible with the AIM clutch.

Switched over from another brand and the BelRay makes it shift much better, along with making it easy to find neutral.I would recommend this product.

Effettuato il cambio dell’olio si avverte la sensazione di una frizione più morbida. Di colore rosso per individuare eventuali perdite e al tatto molto fluido. Secondo me un ottimo prodotto

Was using HD3 in my primary on my 2012 UL. Worked ok until I swapped out the cams, then the clutch would slip in the upper torque range. I switched to this product and now it works great. No more slip. Have bought it 3 times now. Good stuff.
