Forgive me for posting about a topic thats probably been beaten to hell but i tried searching and i cant come up with anything, whether im doing it wrong or not i need to get to the bottom of this... I dont have a manual and i need to do an oil change. I have a 2006 636 and i dont no what kind of oil to use. I know that it needs to be a synthetic 10W-40 oil but any thing i can find is for vehicles over 75,000 miles and its not the right kind of oil to use in a motorcycle. Does anyone know where and what kinds of oil are good to use in this machine. I dont no why i am having this issue right now but i just dont feel like paying 8 bucks a quart for kawi oil at my local motorcycle shop.. Again silly question but any help would be appreciated.
