Check out the following glitch if you have Patch 1.04. To perform it buy the Bati801 motorbike and then pause the game. Select 'Options' and set 'Spawn Location' to 'Last Location'. Take the Bati801 to the Los Santos Customs car shop and customize it as much as possible so that it's value greatly increases and then sell it. Immediately after selling the Bati801 pause the game and select 'Online' followed by 'Swap Character'. When the 'Character' selection screen appears choose the same character you were just using to sell the Bati801. If done correctly you will spawn back on the Bati801 you just sold outside the Los Santos Customs car shop and still have the money you received for selling it. This glitch can be repeated as many times as you want to get the desired amount of money. It is possible to make $5 million an hour using this glitch.
