Great primary oil
Love this primary oil. Shifts smoother. I also use their 6 speed transmission oil when I do my 3 hole oil change. Worth the $$

Reliable & Premium Primary Chain case Oil
I could not find this product with any local vendors but I managed to find it online and it arrived in a rather short period of time. I used this oil on the main primary of my BigDog Ridgeback Chopper and this was after doing quite a bit of research and bottom line is you want to use a good product that will not cause you headaches down the line. I highly recommend this product because it is reliable.

It didn’t make anything worse. Or better. But it worked. I’ve been a Amsoil guy for years Amsoil primary fluid, Amsoil v-twin gearbox oil, and Amsoil v-twin 20-50. Hard to beat
