Here's what I have so far I plan to purchase:

Nerf Bars
Full Body Skidplate
SuperTrapp ISD2 Quiet Series ATV Full Exhaust System
K&N High Flow Off Road Air Filter
CDI Box

I really don't want to do any engine mods like cam, carb, porting, etc. What else should I add or change to this list if you have expert advice? Do I need to re-jet it and if so what sizes to get I would have no clue. I'm in MO.

 

The cdi box is something that isn't needed on a 300ex, mabe a 450, but not a 300ex.Go ahead and get verything else. If you have extra $ go ahead and get a Dyno Jet kit (it comes with everything you need for rejetting), port and polish, and get the flywheel shaved, and get an aluminum swing arm skid plate. When running the new air filter you will want to run it with the airbox lid ON. You get better velocity that way. If you have anymore questions just PM me, I like giving advise.

 

I meant to point out that the supertrapp is kinda overpriced, the FMF powercore 4 is only $270 and is USFS approved also.
