I just changed all the fluids in my 2000 Road King - I put 3.5 quarts in the main, 1 quart in the primary and about 24 oz in transmission. I used Mobil 1 vtwin syn in the main and primary and redline vtwin transmission oil with shockproof in the transmission. There was no whining noise before I changed the oil, but now after changing it, there is a whining noise that is coming from either the front or the primary, its hard to tell. I did a search and found that the common issue was the primary chain being too tight, but there was no noise before the oil change. Is there just not enough oil in the primary?

 

1 qt is enough for the primary ,, check chain , or mabe ipb is getting ready to go

 

Hmm, old oil = no whine, new oil = whine, I'd say put the old oil back in. Is the whine there all the time? In every gear? With the clutch engaged or disengaged?

 

Would you like some cheese with that? J/K of-course.

Not enough info OP.

What fluid was in the prior to the change?
What fluid did you put in?

How much fluid does the spec call for?
