Yes, I am a newbie, already you way more than me in the dirtbike thumper world. So I will play the charector that asks really dumb questions that you will smack your head with you hand for a few months. First, I love Yamaha! My humble opinion is the 1975-78 XS650 is my all time favorite bike. But been wanting a dirtbike from some time now and the wife finally said yes. But I have a questions for the group, because I do not have a manual for the '02 Wr426f. 1. How many quarts does my bike take of oil? Shell Rotella or Mobil1 full synthetic good for it? 2 Link to easily adjust the valves or a 'how to' page. I probably should do this regardless. Any helpful suggestions related to maintenance of the bike is always appreciated.
