just bought an 06 road king friday night....and i love it! only thing i can hear 4th gear a little more than the rest i'm not going to call it a whine because its not that loud at all just can tell alittle difference between it and the rest of the gears....i ordered some fully synthetic spectro 5speed tranny oil will this solve the issue? it has H-D primary/tranny oil in it now. i've herd how good the 6speed spectro is for solving 5th gear whine on 6speed trannys but mine is a 5 so i was reluctant to order it because mine is a 5speed,i'm thinking just forget it and ride it,what u guys think?
