wow this is depressing :(

ok so my quad has been smoking for awhile now and we thought it was most likely the valve seals. also the clutch has been acting funky, like jumping in gear. even when we adjust it, after a couple miles it goes back to the same old crap. also the other night we found metal in my oil. keep in mind my quad is only 9 months old.

so since my warranty ends in march we figured, what the heck lets take it in and see what the dealer says. we let them have it and we ask them what there guess is.
well they said the smoke is probally from the seals,rings, and piston. we didnt metion the metal in the oil, cause that would most likely stomp out any hope of the warranty covering it. but we are assuming that the metal is from the rings and piston.
the clutch is either gone bad, or the cable is strecthed.
now they also said that warranty only covers defects not wear and tear. and there's a chance they wont cover this in the warranty. we asked them the estimate if worse comes to worse, and they said 1200-1500 bucks. so if the warranty doesnt cover the rebuild then we dont know whether we will pay them to rebuild or just put a new engine in it. but one thing is for sure if honda's warranty doesnt cover the rebuild that will be the last honda we purchase. the reason i choose the 400ex over all the rest was because of it being the most reliable sport quad on the market. but Im having more trouble out of my 400ex than my buddy's z400, and his cousin's 450r.
sorry guys just needed to vent, this is just to depressing

Sorry about all the stuff your going through with your quad. I know most warranties dont cover wear and tear. My uncle got a few Yamahas and his warranty is the same way.

thanks, i honestly think i got a lemon. i mean this is the exact opposite i heaard on every review and my buddies. they all said the 400ex is the most reliable chain driven sport quad. and there are yfz's going longer without any problems than i am.

Yeah...Ive heard the same thing about the 400ex. Well...maybe a new quad is in your future?

yea my dad said if honda's warranty doesn cover the work, we'll rebuild it, sell it, and put that money down on a ltr450 or another 450.

Sorry to hear that Chris. Mine is an 05 I bought new and haven't had a lick of trouble with it. The only things I've had to fix were things I broke myself. A new LTR would be cool though!

All of the things you mentioned ANY MFG would label as either wear and tear or not taking care of it. I'm not saying you didn't but no company would cover that.

That flatout sucks!!!!!!!!! Same reason I will not own another GM product.

but on a 9 month old quad? most of you know how maticulous i am about my quads. they're trailer queens.
im going to b*tch theyre ears off till i get my engine rebuilt. and if they still dont want to, ill either have somebody with knowledge on the subject help me, or take it to a machine shop.
i know one thing is for sure, i will probbly never buy another honda product. boy my buddy with a suzuki will be eating this up

but on a serious note, please pray for this to work out in our favor you guys, because we definatly need it.

That is the 1st Honda I have EVER heard og going to crap that fast.
