New Bike Hesitating / Sputtering

[GoldOxide_imp]

mine had same issue when i bought it very low millage and i changed the plugs and it ran great and still is today 4k miles later it would almost die when cracking the throttle at low speed

Try going back to regular unleaded and evaluate if the root cause has been cleaned out?

If not, then the real problem is just being masked.
