I've had my 400ex since last May and its almost completely stock....but now its just too slow for me. I don't want to race it or anything (just yet)....but what can I do to give it some pep? Weight's not really a problem (I'm a girl)...but I've heard that an aluminum frame would help somewhat...anyway, anything would be helpful!!

 

There are lots of things that are available for the 400ex that are far less expensive and less work than the alum. frame. Post this thread on the Honda forum and you will get hundreds of suggestions. You could just search the honda forum for 400ex performance and get all the past topics about it. Good luck

 

if your looking for a cheap way to add more power get a k@n air filter and a pipe, you can also bore the motor, lol or our could just sell your 400ex and buy somethin else

 

wow...a quad girl that rides a honda.!!...welcome to the forum!
