I use Amsoil in all three holes in my twin cam it quites my rocker noise and the trans shifts much smoother and can find neutral way easier. I LUV THIS OIL
I switched over to the AMSOIL for the same reason as the transmission fluid, I don't think you should run motor oil in the primary. I'm getting easier shifting and the clutch doesn't sound like it's trying to slip when I roll on the throttle hard.

I do ocassionally allow HD to do some servicing on my bike but I always take my own Amsoil and insist they use it or I will take my bike elsewhere. Amsoil products are so much better than theirs and I want my bike engine to last a very long time and to always be ready to go on extended trips when I want to go.
Bottom Line
Yes, I would recommend this to a friend.

Great stuff, all I use in my bike. Fast shipping and customer service is great.
After changing to the Amsoil primary fluid, My clutch is smoother than it ever has been. I have changed the fluid multiple times according to the service manual, and the fluid comes out fairly clean each time. This is a perfect upgrade for a good smooth clutch on your Harley Davidson.
Bottom Line
Yes, I would recommend this to a friend.

Bike shifts noticeably smoother and finding neutral is considerably easier. Yes, my clutch is adjusted properly. This is just a superior product. Spend the extra money and your bike will thank you.
A kit would be great, include the seal and plug o-ring. I went to HD to get the seal and they include 3 o-rings. Now we have to store somewhere I’ll remember. Ha
