New Exhaust?

u don't need a jet kit u just need to rejet. u can but jets invidually they just need to be sizes that are richer
 
you made the right choice on the pipe, lrd is the best you can get. jetting is nop big deal. your clip is adjustable so all you need is to try out different main jets. you can buy main jets for around 5$ a piece from your local atv parts store.

as for you actually jetting it... well, you really need to have a feel for jetting a bike, if you have never done it before you have some reading and learning to do.

fell free to ask me if you need help with jetting when the time comes, i can tell you all you need to know, its to much to post right now lol
 
you may not need to jet you blaster. the only way to find out is to run it see how it runs. there are tons of posts on here about jetting and im sure you can find the information you need. i have a FMF fatty pipe and Power Core 2 silencer and i only need to put in a new 250 main jet.
