Hello everybody just became a new member of this site and will soon be a new owner of a 400ex this will be my first sport bike I've ever owned but have been riding utility atvs for a couple of years now was just wantin to know some tips techniques mods things to watch out for..anything would be much appreciated the bike already has Graydon proline exhaust jetted and k&n air filter not sure what the jets are and I've never heard of the exhaust before would like some input on that as well..thanks

 

HMM- watch out for any extremely loud ticking. UM....

..it's a honda- pretty much indestructable.

Front suspension is a common upgrade as some compare the 400's stock suspension to pogo sticks . Elka, fox, HLS, works, or even 450r shocks are common-

tips- it would all depend on what kind of terrain you ride.

 

Yeah I've heard bad things bout the 400ex having a bad valve tick or timing chain tick espically if you change the cams out I was lookin at the hot cams stage one..any input on that?..and also I've heard the shocks suck bad looking at doin the 450r shock swap once I get the money..I will be doin alot of trail riding tight trails lots of corners and hills and possibly riding some lake bottoms um I do have another question how long should an o ring style chain usually last..about a year?

 

Just depends how much you ride. My wife has a 0-ring chain on her 400ex and its been on their for 2 years and its still in great shape but I take the chain off and clean it about every other month due to we do about 200-400 miles a month riding our quads.
