With Glider on this 99%.
SNY 3 is an ok engine oil not bad not the best not a true SNy there for not able to provide the protection of a true SNY.
There are far better true SNY oils. any of witch are high quialty.
Tranmission would you put gear oil in your engine? I think not then why try to get away with engine oil in gear box.
Two different sets of gears 6 speed and 5 speed.
Spectro Platium for 6 speeds is IMO best for both
Redline Shock proof heavy is a great option of either one
then you have other High quialty products that work very well M1 gear oil , royal purple ect. Any of witch are far better than SNY3.
Primary for the most part thinking is and has been no sny in there HD F+.
However new way of thinking new products Spectro and Redline make Lubes for the primary that are sny and they claim are prfect for primary now.
THEY ARE MADE for primary special additives to protect the clutch.
I am trying the redline in both my bikes in the primary now. I trust these two companys.
Last reason if for no other not to use SNY3 is HUGO. If you need Hugo explained just ask.
Nice bike enjoy your ride
