Well the stock main jet is a 120. So just bump it up to a 125 main if you want.

i wouldnt even worry about it, i uncorked my baffle and it ran fine without jetting changes, but mine is an 05 so it might be different
yea go to a size up or two... but one size up should do it for sure... if ur running lean.. i know my stock quad ran a bit lean as i kept getting popping on decel and couldnt rev out all the way most times..
if u bump up a size and ur getting popping might have to richen the fuel screw a bit aswell
or get a slipon and go a two bumps up to 125-130
