[QUOTE="Quailchaser, post: 921515, member: 50691"] Yes. Maybe. Not if you don't want to. First thing is that if you are running rich and you change your ratio from 40:1 to 50:1...you now have made you mixture even more rich. 50:1 is more fuel to oil than 40:1...which means that there will be more fuel to air as well. Do a search on this and you'll find all kinds of technical talk that explains this in great detail. My suggestion would be to run whatever oil you want and mix it at what ever you want (ie. 32:1, 40:1, 50:1, 45:1...) and then stay with that and jet according to this and the environmetal issues. I would also say that it is way hotter this last few weeks here in the Southwest than it was in prior weeks. My bike ran way richer this weekend (110 degrees) than it did two weeks ago. Looks like it's finally time to go to summer jet sets. Later Robb [/QUOTE]
