I purchased this bike last spring and the first thing I did was change all of the fluids. It runs great except in the colder months untill it is fully warmed up, it will not shift into any gear. It grinds and will not shift into gear. I adjusted the clutch as per the factory Harley manual with no results. I don"t know what fluids the original owner used. I posted last night and got great advise as to what tranny fluid to use. I am currently using Castrol 85-140. My question is would the lube actually prevent it from going into gear? It was fine in the summer. The bike is stock. It shifts fine once warmed. I waited my whole life for this bike and it was well worth the wait. Thanx for all of your advise guys. Bus Driver.
