Sorry for the delay in response but I got sick and have been off my computer.
I don't have specific question but interested to hear what others have only found out once they did it themselves. Miles and times dont really say much - its the details along the way that I'm curious about. The most I've ridden in a day was just over 320. Found that my throttle hand would go numb from holding a position too long. I'm going to buy a throttle clamp for it tomorrow and hope it helps significantly.
Thanks for all the links. I've read the their tips section and will have a read at the others
