PRODUCT OVERVIEW

Product Applications
Meets and exceeds primary fluid specifications for Harley Davidson®, Triumph® and pre-2013 INDIAN® bikes.

Product Description
AMSOIL V-Twin Synthetic Primary Fluid is purpose-built for bikers who prefer a dedicated primary chaincase lubricant. Its balanced formulation delivers consistent clutch feel for confident takeoffs, helping riders avoid killing the engine. It also protects components against wear to help riders get the most out of their bikes. V-Twin Synthetic Primary Fluid is Warranty Secure™ and will not void your motorcycle's warranty. It is a cost-effective, high-performance alternative to original equipment manufacturer (OEM) fluids.

Delivers Consistent Clutch Feel & Smooth Acceleration
V-Twin Synthetic Primary Fluid is formulated with a balanced additive system that provides consistent clutch performance and feel. It helps riders easily find neutral and promotes smooth acceleration, whether in stop-and-go city conditions or when on the highway. Its superior load-holding capacity helps prevent clutch slip for confident takeoffs.

Protects Against Chain, Gear & Bearing Wear
V-Twin Synthetic Primary Fluid contains a heavy dose of anti-wear additives to protect the gears, chain and compensator bearing from premature wear. Its superior film strength helps protect against shock-loading, promoting reduced wear and longer component life.

Helps Reduce Operating Temperatures
In extreme heat, V-Twin Synthetic Primary Fluid's thermally stable synthetic formulation naturally resists the harmful effects of thermal breakdown. It helps components stay cool and achieve optimum performance and life.

Maximizes Energy Efficiency
V-Twin Synthetic Primary Fluid's balanced formulation reduces energy lost to drag in cold-temperature riding conditions. It promotes smooth shifts at startup and maximizes energy efficiency.

• Delivers consistent clutch feel for confident takeoffs
• Helps prevent clutch slip
• Provides smooth acceleration
• Helps riders easily find neutral
• Protects compensator bearing, chain and gears against wear

Service Recommendations
V-Twin Synthetic Primary Fluid is recommended for up to 10,000 miles or one year, whichever comes first.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

In the first 600 miles on my 2007 Ultra Classic I was bothered by a constantly moving friction point with my clutch. Sometime it would grab. Sometimes it would work just fine.

I've had perfect clutch action for 58,400 miles. Auto tensioner ware block looks new too.

Cool Running's

It's pretty simple, there are two things that will kill any V-twin engine, heat and friction. So engine oil is one of the most important things to consider, because it has to eliminate friction and be able to withstand high temperatures without breaking down. I use AMZOIL because it is the best lubricant available, and to help it so it's job, I use Love Jugs cooling fans to keep my engine from ever overheating. Between those two things I can feel confident on a long and trouble free engine in my 2012 FLTRU. I also use AMZOIL transmission oil and Primary oil and now have over 48,000 trouble free miles on my ride.

prefer using a dedicated fluid do not have enough miles since changing to amsoil to determine long term effects
short term is shifting it softer no clunking neutral easier to find

Great addition to Amsoil's HD products

This primary fluid does a great job lubricating and quieting the compensators that are known to be noisy for HD 103 engines.

We are talking HOT!!!!

Prior to setting out with my sons on our annual motorcycle trip, I changed the oils in our Harley Davidson touring bikes, a CVO Ultra, CVO Road King and a Screaming Eagle 103 stage 4 Road King. We used AMSOIL V-Twin Primary, V-Twin Tranny and 20w-50 Synthetic V-Twin engine oils.
We then proceed on a two week, 3500 mile journey through Arizona, Nevada, and California in temperatures ranging from 38 degrees to record breaking heat as high as 118 in Death Valley CA. A few days the temperature never dropped below 100 degrees. Averaging 300 miles a day, the HDs performed perfectly. While others in our group of 14 bikes had a variety of lubricant related problems, our AMSOIL equipped motorcycles had zero issues. Not surprised, I've been using AMSOiL products since the late '70 and have never experienced a lubrication related failure with any of my vehicles or equipment.

Excellent product

I have a 2004 Heritage Softail Classic with just over 60,000 miles on it. I've always used Amsoil 20w50 in the transmission, motor, and primary. I switched from 20w50 Amsoil to The V twin primary oil this year. I feel it gives better protection to the inner workings of the primary.I also switched to Amsoil transmission fluid. I still use 20w50 Amsoil in the motor.

Great clutch grab, maybe too great.

Switched to a dedicated Primary lube, due to the OEM Synthetic taking out the transmission roller bearing on a long trip and no longer using one in all three. Noticeably smoother and less chain slap when shifting. One note though is the clutch really locks in so you need to have it adjusted correctly and pull it all the way in especially for 1st and 2nd.

Should have done it years ago!

I finally broke the Mobile habit and am very pleased so far. I did the engine , transmission, and primary as well as oil filter all at the same time. Took a 1500 mile trip from Houston area to Near Branson MO. and was really pleased with the improved noise reduction, smoother quieter shifts and lower oil temps.
I will probably change all three fluids again at 5k miles and inspect. I do not anticipate replacing any of the products I am now using. Couldn't be more satisfied.
