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?
