Has anyone used auto-matic trans oil in thier primary?

 

Yes,

Recommend for some clutches, especially barnett.

Lots of info on forum via sesrch function

I run ATF in my cvo with a 120r as it was recommended by barnett for the clutch i installed. I see little difference vs oil.

 

Me too. You will eventually be told that it will kill your bearings, won't lube the compensator and chain, yadda yadda. All I can tell you is that it hasn't harmed any of my components nor has it done any damage to the 3 other local riders' bikes I know personally. We all use Type F fluid.

Only bad things I've heard about have happened to a guy that some friend of this other guy said he saw at a dealer once.

 

LOL . Exactly. !!

 

I have yet to see a post from someone with a first hand, personal experience with a primary failure due to ATF in their primary. Doesn't mean there isn't one out there, I just haven't found it.

 

Use it, love it, recomend it. Much improved clutch feel.
If you enjoy a soft, forgiving clutch, stick with the stock goo. If you prefer a more positive feeling clutch action, try the ATF. Its not like it aint reversible. You don't like it, change back.

 

I've been using Amsoil 10w40 in the primary for over 10 years with no issues. Never tried ATF fluid.

 

Why use ATF? Any gain.

 

Gain? Like horsepower gain, no. Its simply a thinner, clutch pack friendly fluid that gives riders different feedback than the much thicker, heavier oil that the factory uses. Once it works its way threw the clutch, you will notice a difference. Most people who try it, love it. Some people hate it. I feel as if my clutch grabs better, but that's just me. Countless armchair scientists will argue endlessly about yellow metals, "the manual says", and all the "I heards" one can throw a stick at. But in the end, its oil, it charges the feel of the clutch, and its your bike to either try it or not try it.

 

i've used, 10w30 motor oil,10w40 motor oil, the harley primary oil and atf. i can't tell the difference between any of them so i use atf because it's cheeper. 85 flh with about 100k on it and the original clutch still in it.
