Hi/low switch is broken. Looks like it has gone over on the left side, replaces lever/bracket and doesn't have the original hole for the mirror, hence the new type of mirrors. Check for bent triple or fork.
Fuel stains on the right engine cover. All of the things he has done is refurbishing to a level of maintenance. Brake lines look to be original, so i question what has been done to the brakes. Rebuild or dismantle, free up and put back together?
Chrome guards/muffler and tank look polished but the motor, rear shocks, headers don't look nice.
Take any rose tinted glasses off before looking at this.
