About to buy an '04 Raptor,
 

I just bought an 04 on friday. I asked the dealer about problems that I should watch out for. He told me about the one way issue. I also asked the mechanic about it, and he told me to make sure that you do not start the bike in gear. He also told me to let the bike warm up before I do anything. He said the majority of the one way issues he has seen are on bikes with mods.

Just my 2 cents, and I don't profess to know it all. I am happy with my purchase, and good luck to you.
