how do you change the oil in a 89 blaster loll

warm up motor, pull the plug under the motor drain oil, put 650ml back in the right side fill hole.......atf is good to use
 
just dont use any oil thats not ment for a wet clutch, being more technical, no anti friction additives, it will kill your clutch.
 
where do u buy your oil from and what brand might I ask?

I use amsoil 10w40 motorcycle oil and went all summer and winter and still has a golden look.
 
I asked the guy at the shop what I should use he said atf synthetic if I'm riding hard. Just be sure to change it pretty often.. Anyone else use this?
