I have a 2018 XL1200X (Forty-Eight 1200 Sportster) that is due for it's 1,000 mile fluid change.
As the stealership want ridiculous amounts of money to do it, I am doing it myself.
There seems to be 2 schools of thought on this fluid change. Since the sportsters are 2 hole affairs,
some say you can use 20w50 for both engine and transmission/primary chain...while others say you are better using the 20w50 in the engine, and gear oil in the tranny/primary chain.
Dealer service department recommends 20w50 in both. Lots of ppl on the web say they use 80/140 gear oil. I am using Mobil 1 V-twin 20w50 synthetic in the engine oil change.
Here is the first question: Do you use synthetic or dino gear oil or the 20w50 synthetic or dino oil in the tranny/primary?
Question 2
Do you remove the clutch inspection cover and add the tranny/primary oil there, watching to reach a certain level, then replacing the cover, or do you simply add 32 oz to the tranny/primary throught the chain inspection port?
Thanks for you responses.
