I found that I had lean help on when I set multiple fast lap times. Now I'd like to reset them because they are too good for my current skill level. How do I go back and erase the best lap times to get a new trainer/ghost?
You can, it will be deleting a file in your Game Documents folder.
Go to: Documents > PiBoSo > MX Bikes > profiles > (your profile name) > records.ini
Once you are in there, you can find the track and the bike you want to delete, or just delete everything inside that file to get rid of all of your records.
Thanks!
