Mine is a 2004 400at, bought it new and 3 weeks later I got a whining/grinding noise from the tranny/engine area whenever I climed a steep grade or drove it up the ramps into my truck. I took it back to the dealer, they said they couldnt get it to make the noise, a month later it did it again, this time it was easy to get it to make this noise! This time the dealer did some work and when I went to pick uo my "fixed" bike it had blue gunk where they had pulled the motor apart and resealed it after changing clutches and doing a few other things that I cant remember, nice for a brand new bike huh! 1 year or so later and the same thing happened, the bike went back but this time no warranty, $1500 later and I had my bike back, I rarely ride it anymore but 7 years and 4000kms (2800mi) later she is doing the same thing! I hate this pile of garbage bike and will NEVER own another Honda (atv) as for the claim by some people on here that Honda cut the 12 month production run on these bikes to 10 months because of price, well Ive had two dealers tell me that honda cut the prod. run because of quality! Honda shoul have come good on every bike sold in 04 as far as Im concerned! If my generator and pressure washer werent so good Id be sure to never have a Honda brand again, I even told the dealer (after my sixth visit in a year and a half) if I wanted a broke down POS I woulda bought a goddamn Polaris and at LEAST have something that rode nice!!!!
