All the time, in the models with the "good" compensator.

I've used it for years on an '01 RK with a Pro clutch. Right now just running cheap O'Reilly's atf.

Use it. B&M takes the heat better than regular ATF, your clutch plates will like it.

Hippo said his order of preference was

1: Redline MTL
2: B&M Trick Shift
3: ATF

Been using it for years on several bikes, was originally recommended by the folks at Energy One. None of my HD's are newer than 2004, so with the '07 and newer comp, I can't offer any experience

I think the Dextron 4 (up) is synthetic.
John Deere also has some synthetic ATF.

Read that it wasn't good to use Syn oil in a primary.
Question is: Why would you want to use something made to slip on a clutch you don't want to slip?
Yes. No. Maybe so?

The reason most recommend something else other than that Syn3 is because of the severe conditions with the compensator. It has nothing to do with the clutch. Many recommend good old Formula+ for the primary. There is some that run various brands of ATF also generally because they are running an after market clutch. Nothing wrong with synthetic in the primary as long as the compensator likes it.

Energy One instructs not use synthetics as it can cause their clutch to slip. Just about anything is OK for the chain it's the comp and clutch plates that need to play well with lubricant. Old comps are not fussy, the late pieces of dung are finicky.

Ok. I have an 18' Heritage. Using non Syn 20-50 Castrol.
Does the comp like that or Syn better?
Dealers put Syn 3 in there.
Thought Dino would be better!

Your EVO compensator is not likely to give you problems, it's the Twinkie compensator that "potty mouth"s up.

I would not use Synth MOTOR OIL in my primary, but I would use Synthetic TRANS fluid.
I have seen Synthetic motor oil cause a clutch to chatter or moan when slipped under power.
Never with Synthetic ATF.

Note: all of the new style trans fluid is synthetic AND it's made for clutches.
