My initial run after switching to Amsoil for my bike (Heritage Classic 114), easy to shift with less noise. I should mention that it was 10C (50F), during my ride and it was a short ride at that. Weather is not co-operating for an extended ride. My observations on the oil may or may not change after the oil reaches a higher operating temperature.
Bottom Line
Yes, I would recommend this to a friend.

I had the SYN Harley oil in 2012 Road Glide and seen a video on face book about the product.. Should have did a long time ago.. It is like NIGHT and DAY..The clutch is so much smoother.. quiter and so much better.. Like a new bike.. So much easier to change gears now……..
Bottom Line
Yes, I would recommend this to a friend.

80,000 miles on my bike and just rebuilt the engine for more performance. No discernible wear on Cam, cylinder walls, piston / rings, compensator or clutches. Changed everything for high performance parts but old stuff was amazingly looking pretty good.
Bottom Line
Yes, I would recommend this to a friend.

Should be as good as the Motoroil and primary fluid

I switched to the V twin amsoil motor oil, noticed the engine running cooler and quieter, so I did the primary, the whirling noise disappeared, so I switched the transfered as well. It's not immediately noticeable but the improvements from the other 2 fluid changes sold me. Done.
Bottom Line
Yes, I would recommend this to a friend.
