Default few questions about servicing

New owner here. I just bought a 03 fxst a few days ago and need to service it. I have owned jap sportbikes for years but finally decided to switch. The oil changes are completly different on the harley. I picked up 4 quarts of mobil1 20w50 and a harley oil filter. I am going to change the engine oil and tranny today. My question is how much oil goes in the oil tank and how much goes into the tranny? The dealer told me to use the 20w50 in everything but reading on here 75w90 seems popular in the tranny. He said to use 3qts in the tank, 1 in the primary, and 24oz in the tranny. Is this correct? Is there a way to tell when the tranny is full? Any other tips? I did not get a owners manual so I am flying blind.

sounds like the dealer set you right.
start with 3 qts. in the oil tank for the motor. run it & check the level.

24 oz. for the tranny sounds good too. start with that & check it with the stick. i thought i remembered it taking maybe 28 ozs., but my memory sucks.

i'll let you make your own decision on what oil you use where.

don't forget the primary.

and congrats on the new to you ride

Mobile Vtwin 20-50 is rated for all 3 holes. Reg. Mobile 1 contains friction modifiers and should never be used in the primary or so I heard.

I won't be the only one to tell you to get a manual, but there is a lot more than oil you need to service on a used Harley. I would also use the KN filter instead of the HD filter. It is much easier to take off, next time around.
You can find a manual on Ebay pretty cheap.

I know I need to get a manual. The bike already has the k&n, jet kit and screaming eagle pipes so I am good there. What else needs to be checked at 10k miles?

Good reason to get the manual, clutch adjustment, and cables adjusted and lubed, wheel bearings, neck bearing, fork fluid, and lots more.

My indy gets $300 for the whole kit and kaboodle. and suggests it be done every season, which seemed excessive, but his RK has 95000 miles on it and looks, runs and rides like new.

A few more questions and I am done. Do you push the dipstick all the way in to check the oil? Pushing it in and not is the difference between full and low.
Is the tranny drain plug the one in between the 2 shocks? I see there is 1 on the bottom of the motor, 1 on the side of the motor, 1 in the primary, 1 in dtween the shocks then the oil plug. Thanks.

yes, engine oil tank cap/dipstick all the way in to check level.

yes, tranny drain plug located between the shocks. the one on the right hand side near the swingarm is for the engine oil tank. it's connected to a hose that goes to the bottom of the tank.
