When hot it runs erratic and unable to select gears. No management code shows. When cool, runs  ok. Could it be a spark plug issue?   It is a 2019 model, 650 miles.

Have E5 symbol on dash, indicates air inlet pressure sensor problem.
Where abouts is the sensor located ?
2019 model just purchased, and no knowledge of quads, only motorcycles.
I am in the UK, just joined,  so hello to you all.
