I have a 2007 300ex, everything is stock execpt the UNI air filter and back tires(dunlop kt175 that kame in todayartsin01: ). I always hear that 300ex are well rounded quads, and mine seems just fine for me. I can somewhat keep up to my dads 440ex in the trails but on straights i cant even come close. So i was wondering what kind of upgrades can i get for a bit more power and speed. I dont have the biggest budget so keep that in mind, thx.
