you can change the gearing go up one in front for top speed down one for torque you could also race cut the fenders so less wind hits them.a lil more expensive option is tires get bigger ones for top speed smaller for bottom end.

only get the cdi if you are hitting the rev limiter a lot. It really doesnt do much unless your motor is beefed up.

Get exhaust, and a K&N. Loose the top of the box, and rejet it. You will see some nice improvements.

Thanks Yam, people like you make this world a great place to live in. Exriders is a great site if you are looking for info on anything Honda (quads). Do a search on 400ex mods and you will find plenty to help you make a well educated decision without dealing with some of the immature children that ruin a perfectly fine forum.
