I recently got a 2006 all stock blaster with a newly replaced top end. The way I got it was stock jets and an open air box. Now im going to be riding in dirty and wet conditions so should I get an airbox cover for it? If so which one. Also I got a pro circuit platinum pipe, dg silencer, and k & n filter that I want to put on it. What size jet should I put on and if so what else should I do to increase performance. Im new to this stuff so sorry if im leaving anything out. Any help will be appreciated. thx
