I'm not trying to be an asshole. I'm just saying that alot of people lately have been asking, "what oil should I use?", or "what ratio should I mix?". Alot of people say Klotz, then some say Amsoil, and then there's Castor927, or Yamalube, and the list goes on. Then you got people sayin 25:1, or 32:1, and 40:1, 50:1, and I've even seen 100:1. Really, the best thing to do is see what your bike likes. Personally, I use Maxima SuperM synthetic blend at 40:1. I don't think anyone else on here uses that oil. But, I tried it and I like it. Just try the Amsoil, and see how you like it. Really, I would say whatever you use, get either a esther, blend, or full synthetic.
