Greetings! I have an 03 KLR 650. I have added a K-N filter plus a Laser Pro Duro slip on exhaust. I have also installed a Dynojet kit stage 1. I would like to remove the metal screen in the airbox. My question is, is there more power to be gained by doing this and will I need to go to the stage 2 in the jet kit so as not to run too lean. My mileage is in the low 50's now. Thanks,Lewis [Non-text portions of this message have been removed]

The new red KLR is in my garage right now. I think it's the best color ever offered. And by the way, the tank is 75% black. [Non-text portions of this message have been removed]
