Well I bought it and got it home, When I looked at it the other night it was in the garage and it only sounded like a ticking like it was the valvetrain but now that I hear it outside in the open I also think i hear a bottom end noise but then again it may be that Im paranoid, lol. I have a Yamaha mechanic thats comming over tomorrow to listen to it for me and get his opinion . I want to thank everyone who has written to give me there opinion, Ill be keeping my fingers crossed. Ill let everyone know tomorrow what he has to say. Thanks...
