I was reading a response to one of my other posts and it got me thinking about oil. I searched old posts and found a little info but not a lot. What brand/weight/etc.. are you guys running. I just recently switched from Yamalube to mobile 1 sythetic 15/50. I ride mostly SoCal deserts and tracks. I did see some debate between synthetic vs. non in those older posts also. So what do you guys run? Khris ------------------ When in doubt, GAS IT!
