On the recommendation of the HD service department, I put Formula + in my transmission about 500 miles ago at the initial 1000 mile service. This is my first HD so I'm in full learning mode. The bike is a 2013 FLHTK AE. Based on my reading the preferred transmission oiled is the Spectro 6 Speed 75/140.
Should I drain the Formula + from the transmission and switch it to the Spectro or let it ride until the 5000 mile mark? Thanks for your assistance and the recommendations you posted on the site!
