I am considering trading my 2002 warrior (with a ton of work) for a 99 busa. The owner said that it has a big bore kit in it and was rebuilt about 4,000 miles ago. I have owned a 05 busa and I know about some sort of serious starter problem with the early models. Is there any way to tell if the bike truly has a big bore kit? Also what is the remedy for the started problem and is there anything I can look for to see if it has been done? Thank you very much!!
