My 14 year old daughter came running in the other night because the 4 wheeler wouldn’t turn off.

So…
I found an old post relating to this problem.

Symptoms ; Turned bike off and it tried to keep starting then turn key on and it would start but starter motor would continue to run.
Had to disconnect the battery to get it to stop.

The suggestion was to replace the starter solenoid so did that and no joy.

Any suggestions would be great.
Cheers
