when I bought my bike it has syn3 in all 3 holes, I didn't like how the bike performed so I went with Amsoil shockproof 90/140 or in the trans, mobil 1 v-twin 20/50 in the engine and formula+ in the primary. this is the best combination for me so far.............

 

This compensator shim kit, ask your indy for the part number. Wondering minds would like more information on this.

 

Before you worry about putting in a shim kit, switch from Syn 3 back to HD Formula +. It made a HUGE difference in my '14. The compensator was getting really noisy, sounded like hell. I had some formula plus in the garage and dumped the Syn 3 and put that in. The noisy compensator TOTALLY quieted down, no more noise at all now. The synthetic just doesn't seem to have the thicker viscosity formua + does. I was amazed how it solved the noise issue so quickly. It doesn't matter what guys used to run in their OLDER bikes, I will run nothing my Formula + in my '14 from now on

 

F+ works just fine logged many miles with it in primary not one problem on any of the bikes. You just don't need any magic special lube in the primary.

 

Hell yes! Beats Amsoil any day!

 

Same here. No problems at all

 

I used to run synthetic, but was told by someone that does Police Motor Competitions to stay with Formula +.


Synthetic is a little too slippery for the Friction Discs.


I run;


Engine-Mobil 1 V-twin 20/50


Trans-Redline with Shockproof


Primary-Formula +

 

Syn3 is listed as an acceptable option in the service manual.
It even lists it right on the bottle.

The dealers "recommend" this probably because Harley says it is OK.
HD even ships all of their CVO bikes out with Syn3 right from the factory.

I've been using Syn3 in mine without any issues for over 35,000 miles.

 

WooHoo! an oil thread!

 

formula+ for me
