best upgrades for a 1999 yz400f

I love my bike its stock except a uni filter what are the simplest cheap mods to get more power thought the whole power band?

The best mod in my opinion is the 450 cam swap to rid you of the decompression lever and the starting procedure. Do the work yourself and it will cost you between $100 - $150 to do.

A high compression piston and a set of Hot Cams will wake it up. :thumbsup:
