umm a pipe would help out alot...

an air filter, take off the airbox lid is free, exhaust pipe, rev box and a sparks timing key. a good set of tires will make it feel like it has more hp.

Full exhaust without a doubt.

is this a good exhaust to get :LRD PRO4 SERIES FULL EXHAUST PIPE HMF HONDA 400EX ?

LRD Pro4 and HMF are two different ones. They are both good but also loud.

I read a thread a week or so ago that changed my mind about LRD. people were welding brackets back on them and everything else. HMF is a good pipe though. Lots of people have them. Ill sell you one too!

Also look into sparks and white bros.
