Bugs

 * If you saved in front of him and asking for his helmet for the first time, reloading your save-game after he gived to you, sometimes you will see Motor-Runner without his helmet. This bug can be fix reloading again.
 * Even if you ask him for his Motor-Runner's helmet everytime, you will never gona 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.
