I have a FMF Megamax II exhaust w/ a oversized header, I just installed it about 4 days or so and didn't get to run it to see how it performed until today....well I know I need to get it jetted but should it get this hot(I can crank it up and rev it up a few times and you can't touch it or it will blister you hand)? I called a cycle shop and they said a 135 main jet is what I need, is this true? Should I change the pilot jet too?

I have a uni filter and a 2"x2" hole in my air box, I also removed my choke today too. Any ideas will help, thanks.
