I am about to change my oil for the first time, do you guys have any tips on making this an easy task? Or is it an easy task? I went to the dealership and they told me not to run synthetic oil because the clutch will wear out and the pros run synthetic because they change their clutch after every race. I was going to buy Bel Ray 4 stroke synthetic oil but they wouldn't let me buy it. They actually put it back on the shelf and got me to buy Yamalube 10w-30 4 stroke oil. What do you guys use?
