To make a reported speech for a yes/no question, you use 'if/whether' in it beside applying tense shift.
Example:
'Are you alone?'
Reported speech: He asked me if/ whether she was alone.

So, the answer for the blank is possibly in past tense.
He asked me whether he could borrow my motorcycle to go to the party.
