Is it possible to do the airbox mod without jetting? Or will this harm my bike? I don't have the jet it yet, but I would like to go ahead with the 3x3 mod.

Don't do it unless you are doing the jet kit at the same time. The bikes run lean from the factory to pass emissions requirements, and that is with the little airbox opening. By enlarging the opening, the bike will run even leaner. Running lean means running hot, and could cause damage.

Do it at the same time that you do the jetting, it only takes 5 mins.

I put 1,000+ track miles on my DRZ with the 3x3 mod, K&N air filter, and full Yosh system before I put my jet kit in. It ran fine for me. (I do not ride the street with my DRZ...so, the throttle is "wide open" 95% of the time)

To be honest with you, I was disappointed when I put my jet kit in. I could not tell much difference.

Street riding might be a little different.

I was wondering the same thing......

Thanks WRX! I'll order the jet kit and then do it then. If I put on an exhaust later will I need to re-jet it?

Did you notice a big difference from the 3x3 itself?

i am at higher elevation and did full yoshi 3x3 mod at the same time. stock jets. the exhaust crackles and pops at me when i let off but i still idle perfectly and i dont bog down what so ever. im at about 3500 elevation tho. i dont see a need to rejet yet.

Not really....
I live in Florida and ride it on the track all the time (JenningsGP).....I didnt put the jet kit in until 1,000 miles later. I did notice that the exhaust crackles & pops more.
