I was wondering what oil everyone ran. I live in Orlando, and it gets pretty darn hot in the summer (like now!), and I was considering changing to Mobil1 15-50 for the rest of the summer in my '01 Ninja 500R. I just got the bike and I have no MOM yet. The sticker under the seat does not list 15-50 but 20-50 is there, so it should be ok. Funny thing is a buddy just got an '02 500R and his under seat sticker does not even list 20-50. I thought that was wierd. So let me know what you all run, so I can get some idea what I should do. Thanks.
