I recently upgraded my stock 2009 Harley Davidson FXDBI clutch using the Barnett clutch pack with the extra disk. The recommended Primary oil with these clutches is ATF-type F transmission oil.
I am a true believer in Amsoil oil and it toughness to withstand utter all out punishment.
Well a normal Harley rider knows nothing else. I researched others who have used the ATF fluids in their primary and the biggest concern was heat.. I filled and have run this ATF in my FXDB and I am happy with the all around smoothness yet assertive instant response. I have not gone through a heated season with it but do not expect any problems.
I am a believer in Amsoil products. I use it in everywhere on my Harley and and Subaru and just enjoy the protected feeling and gains with better gas mileage with minimal wear and tear.
Yes, I would recommend this to a friend.

I run this in the primary of all my Harley Davidson motorcycles. The clutch runs much cooler and less gunk in the bottom each change. I run a very he performance clutch that has high standards for oil that will void warranty. Super Shift is one of the few that qualify for those specifications.
