If I'm going to change the motor oil, primary, and transmission all in the same day, is there any advantage or reason to do them in any specific order? Nothing comes to my mind but I've been mistaken once or twice in my life!
Yeah, that's why I specified all in the same day, not all at once. I plan to do each one slowly and all the way to completion before starting on the next one.
It doesn't technically make a difference really, other than the efficiency of doing the work, the way I see it.
I drain all the fluids and do the filter change initially with the bike "leaning" on the stand, where all will drain more completely. While still in that position, I install the engine oil.
I then use the jack to lift and level, adding the chain and tranny lube. They both can be checked for proper level in this position.
Finally, removing the jack, running the engine, "finished" engine oil check with the bike back on the jiffy stand.
Doing the work in that order, saves a lot of wasted motion.
