i usually drop the transport oil straight away, although some people say thats a thinner oil that comes with the bike so u can run it in, which is bull.
drop that oil and watch the metal shavings come out along with it.
then put some 5-10w oil in for 10mins run it through get everything lubricated straight away. get a good oil flow going through the new components. then drop it and put your recomended oil in, what ever brand is your preferance. and change after every big ride
