Is this new or used?  If new,  probably shouldn't be at full throttle until the thru break-in period.

Thanks. It’s brand new. Dealer only told me to change the oil at 50 miles. What was your rpm limit for the break in period?

Hi new here. Just bought a Massimo Buck250X for some neighborhood riding. New unit rides great and seems to work fine, except when full throttle for 5 min or more the check engine light comes on. Air filter is fine, and oil is topped off, any ideas? 
I figure it’s just a sensor issue but I’ve been wrong before.
