looking for easy and cheap performance mods

I've got a 400ex and am looking to spunk it up a bit. I've changed the pilot jet to a 42 and have added a twin air filter, and cut holes in the airbox lid. I've removed the baffle on the muffler and added a twist throttle. I was wondering if i should change my main jet to a 150, and have thought about adding an aftermarket muffler and changing the cdi box. I don't want to bore out the engine or anything too extreme like NOS (although mite be fun) Does nebody have ant thoughts or opinions?

CRT Performance offers a SWEET Stainless Steel Reusable Oil Filter that has far superior filtration than any paper style filter. It also can be completely disassembled and thoroughly cleaned at each oil change. They also offer a 100% LIFETIME WARRANTY. It is made of Billet Aluminum, Stainless Steel filter mesh, and is Color Anodized in Team Colors. Check them out at: www.furious-flow-filters.com
I've got them in my two bikes and they're SWEET!
