I don't think you need to run out and drain it and replace it early. However, I do strongly believe in Redline products. To each their own; however, I wouldn't just drain it and throw the Syn3 away. One maintenance cycle with Syn3 won't hurt you at all. Ride it and enjoy!!
I like the Redline Products as I have had Many HD's over the years and Never any Lubrication problems using their fine products... The thing I believe about the HD syn 3 is It was designed for the all three Holes... BUT Not in My book.. You Can't take a Engine oil OIL and call it a GEAR OIL.. that being my Pet Peeve here...
I have used Shockproof Heavy in my tyrannies from first on.. NEVER EVER ANY METAL on the magnetic drain plug NEVER......
That in it's self tells me that the GEAR OIL is working... And the added Shockproof is cushioning Gear to Gear and NO wear on them...
I have had a person Buy a new bike, the 08 RG and call me after he bought it and ready to take it back to get his Old bike back.. Saying the Tyranny Makes Terrible Noise....
I gave him a Quart of Redline Shockproof Heavy as He Scoffed the Idea....
An Hour later He called and Thanked me for the Gear oil.. The NOISE was GONE.... Not just less BUT GONE...
He found out later that the HD used SYN# in all three holes... I believe he replaced with Amsoil in the engine and the primary but KEPT using the Redline Shockproof Heavy...
Many here Debate the oil and some will say that Nothing Wrong with syn3 ,,,but USING IT is not good in MY BOOK...
Even Glider will suggest Not in the Primary or Tyranny as syn3 is Not Made for that Regardless of HD's stated use..
Even HD backed-off using it in all three holes...... There are MANY other GOOD lubes and gear oils Better for the Job..
I WOULD NOT leave SYN3 in the Primary OR Especially the TYRANNY.. DRAIN IT OUT.....
If you want to go with a HD product in the Primary use Formal+
In the Tyranny use Redline or Spectro NO SYN3....
