(2007 CRF250X) Can I rejet and still run the stock pipe until I can afford to buy an after market pipe? And if I can rejet with the stock pipe, do I need to replace the fuel screw as well? Also, I've read that I need a special tool to replace the jets. Is this something I definitely need?

I currently have my carb off to clean it out (runs with choke on but not without, and stalls if I give it any throttle) and thought that this would be a good time to rejet, just not sure if I need an after market pipe at the same time?
