I have a 2003 raptor this is my first sport quad, i was a utility quad guy before...

Mods in the garage waiting to go on bike-

Yosh Comp rs-3 full system
insaneperformance aluminum box with kn clamp on filter

now my question is i should probally start with main jets 160/165 but on the stage 2 dyno jet they only go to 150 or 155?? Should i try to find a stage 3 jet kit why would they include smaller jets than the stock 140/145 in the dynojet kit?? what jet kit should i get and what would you all recommend for me i want to get this stuff installed this weekend.

thanks,

Jason
