I wasn't trying to be disrespectful. I apologize if I came off that way.
K. I've used syn 3 thinking oh it's harley so it must be Gods gift to my bike. So I rode with a clunky tranny,a hammer going into first,you know the drill.
When I significantly increased the power output these "qualities" became unbearable so on a whim I tried redline shockproof heavy.
Almost immediately the tranny didn't clunk anymore,it shifted smoothly. It was like the tranny finally operated like it should have.
So I suffered for 10000 miles with syn 3. It's been 30000 miles now with shockproof heavy and I feel it's my duty as a harley owner to inform other harley owners that there is a better way,and a better product.
And harley now says to use formula+ and not syn 3 in the tranny,regardless of what the bottle says.
I didn't take anything you said as being disrespectful, no need to apologize. I know Harley has sold their "Formula" oil for a while, and offered Syn III as a alternative trans oil. Sorta like they offer HD 360 motor oil and Syn III as an alternative oil. I've heard several people say that Harley doesn't recommend their syn III for transmissions. I've searched and can't find an official statement from Harley, or a Service bulletin stating that. Could you direct me to one if you know of it.,,,
