[QUOTE="Zrt1200, post: 1442839, member: 124547"] Why would you want to go to Race fuel unless you need it?? It will actually make your bike slower unless you need it to stop detonation from a modified cylinder & cylinder head. The higher the octane rating the slower the fuel burns. That is why if you have say 16 to 1 CR ratio you need race fuel to stop the detonation. On a stock bike the slow burn time of race fuel will make you loose power. [/QUOTE]
