I have read a lot about what type of fuel to use in my 93 Vulcan, most people say that the standard 87 octane fuel is just fine, here in Colorado the standard fuel is 85 octane, is that to low of octane?
Yup, Wolfie is right. Stock vn700/750 is 10.3:1. :rockon:9:1 ???...mine is 10.3 : 1 stock and since mine has only 5k orig miles...mebbe 10:1.....that warrants higher than regular, IMO....
In the 70s....any hot rod runnin 9.5:1 pistons and up, all ran Sunoco 260, which was 98 I believe.....
