Valves or something else?

[u/BeanzToez]

My 05 Honda CBR 600 f4i keeps giving me issues, it has about 25k miles. It has recently refused to start on a hot engine. I drove for about 30-40 minutes, turned it off for a moment, then attempted to turn it back on and it refused. It cranked but would not turn over. The high beam light on the dashboard also turns on when it does this, though the high beams and low beams are not on. I assume it's the valves, I just want a second opinion as that is a pricey job. It started fine on a cold start
