thanks for the input. I know the cruisers put alot of miles on them but I noticed most used sport bikes have low mileage so that kind of worried me. i bought the yzf600 from a guy who just lost his job and needed the money. the bike rides great, no engine noise, no leaking header pipes, i wound it out in second gear to see if it would jump out of gear and it held fine. I cant wait until a warm day so i can put some miles on it. thanks again.
