running pump fuel 93 octane

[iqrjay]

What's is the best setting for timing for running pump fuel with 93 octane. Without hurting motor but still running good or any suggestions on best mixt
for pump fuel and race fuel and at what setting been trying to find this out as I just bought a 2010 iqr 600 and now after reading some forums thinking of selling it. Cause can't figure the timing out. Bit would really like to keep it so I hope someone can maybe help figure it out thanks

Run 32/1 for mix. Polaris recommends Red Line Race oil for the long stroke 600. Run the timing switch on E. Also watch your plugs you may have to add some fuel to prevent detonation on long WOT runs.
