I have decided to get the Viper ported by MRviper700. I am stuck between a stage 1 and stage 2 porting. Stage 2 I need to run 93 octane, and 93 octane isn't easy to comy by on the trail. Anyone here ride the trails with a stage 2 port?

You can run pump fuel on any type of porting job. It is cylinder head design that will depict the amount of octane you will require.
