Thinking of changing all my oil over to Amsoil. I know that my bike 2010 street bob runs synthetic 20W50 in the engine. I also believe that the crankcase is the same. Only thing I am not sure on is what type of Amsoil transmission oil I should use. Any input is appreciated.

Thanks

I use amsoil 20w50 in crank and primary, 75w110 in trans.

 

Amsoil 75/110 in the tranny

 

20W-50 in all of them.

 

....and there ya have it, 3 different replies from 4 different people. I hope this thread has shed some much needed light on your query.

 

Seems simple enough to me.

 

20/50 in engine
75/110 tranny... shifts better ....IMO
Golden Spectro in my Primary....

 

Shifting is all about hitting the mark. If I miss. I feel it. If I don't, I don't hear anything. Has nothing to do with fluids; JMO.
