Why not SYN3 oil? I'm not arguing here, I just don't know. What oil do you recommend? Also, at the risk of looking very ignorant, what's the jiffy stand? ....my whole problem right now is the bike was last serviced, before I got it, at a Yamaha dealer so I don't know what's in there. I don't have the service manual yet so I don't even know the correct procedure to change the oil in all three holes.
