Hellos going to service the ninja 250r and was just wondering if I need to run the bike for abit to warm up the oil before I change it?
Yes indeed!Nope just drain it. Last time you rode the bike the oil was nice and hot and it all drained to the bottom of the engine, where it is now sitting, waiting to be drained and replaced.
You're right, of course.Yes indeed!
But still be sure to let the sump drain well, say 5 minutes or so, especially if the oil is cold season cold.
