[QUOTE="Rich Rohrich, post: 674745, member: 16241"] If you don't see a burn pattern with Yamalube 2R then the chamber is too cold, PERIOD. The look will change with different fuels, but it will be there regardless, [b]IF[/b] the engine is run hot enough. A properly jetted MX bike that is being ridden hard should [b]always[/b] show a pattern with this oil. If you don't see a pattern then you know there is free power just waiting to be unleashed from the engine. The oil/fuel mix doesn't know or care what engine it's reacting in , the chemistry is the same regardless of the color of the bike. [/QUOTE]
