Motor-Runner

"Dinnertime, boys!"

Motor-Runner is the leader of the Fiends, located in Vault 3 in 2281, currently fighting against the NCR in the NCR-Fiends War.

Background
He is found in the maintenance wing with his two guard dogs, BoneGnash and GhashBone.

Quests

 * Aba Daba Honeymoon: The player is told to deliver some drugs to Motor-Runner for Diane.
 * Bounty Killer: The player is ordered by James Hsu or Bryce Anders to kill Motor-Runner.

Other interactions
The Courier can give him various drugs (jet, psycho, etc) for 20 caps (or 22 caps, if the player passes the barter check) if you pass a speech check at the entrance of Vault 3 when speaking to the Fiend at the door.

Appearances
Motor-Runner appears only in Fallout: New Vegas.

Bugs

 * If you saved in front of him and asking for his helmet for the first time, reloading your save-game after he gave to you, sometimes you will see Motor-Runner without his helmet. This bug can be fixed reloading again.
 * Even if you ask him for his helmet every time, you will never give him caps. So enjoy having the helmets for free.
 * Another bug appears to be if you have more than 1 Motor-Runner's helmet in your inventory. The dialog about Motor-Runner death for Colonel Hsu will not appear. This bug can be fixed using, by dropping all the helmets and let only one to be in your inventory. After finishing the quest, you can take them back.
 * Trying to sell ALL of your Jet/Buffout/Psycho from your personal stash to Motor-Runner might not work (option is available, but nothing happens). Selling single doses of Jet/Buffout/Psycho still works, though. Possible reason for this: you might have stolen chems from the Vault 3 Fiends. Since you cannot sell items to the faction you stole it from this option doesn't work. It could also be possible that there is a problem with the player carrying "Dixon's Jet" which is bought in Freeside. Tested on Xbox, the "sell All" options don't work regardless.
 * If you are able to unload your chems on him, be aware that you can't simply pick them back up off his body after killing him. Similarly, the caps he had available for buying your chems do not appear on his body if you choose not to sell to him. Plan accordingly.
 * If you exhaust all dialog options before approaching him for the Aba Daba Honeymoon he may have no dialog and simply respond like any other fiend in the vault rendering the quest incompleteable.
