ok I've read the items in the search and those opinions on hp for the 400 ex are different from what it states on my title. It states 34 hp so is there a difference between the yeasr on them? Oh and mines a 05 just curious if anyone knows, thank guys

 

Well im pretty sure to tell you that no stock 400ex is 34hp.....more like 28ish.

 

I think stock is 27hp.

 

thats cool guys again i was just checking because on my title it states 34hp, does any of your titles tell what the hp is on your atv's ?

 

Is that crankshaft HP or rear wheel HP

 

you know I'm not for sure as it just shows hp and below it 34, but I trust your guys knowledge over what the title says, anyway sorry to waste a post with this but thanks guys for answering me and now the post is dead.
