Default Re: High/medium/ low grade! What octane for your china girl!

It depends on compression ratio, most low compression stock engines run fine on 87 octane. The higher the compression the higher the fuel grade should be. I run 87 in both of my bikes with no problems. I do sometimes run 90 octane pure gas when I think to stop by the only station near me that has it.
Your results may not be the same,Greg
