I've got a 2007 Suzuki DRZ400S, and I put a K and N air filter and a scorpion exhaust slip on silencer on it. So obviously I need to rejet it. I just want to know what brand of jetting kit you would recommend. I've seen about 3 or 4 differently kinds, all from about 50 to 80 dollars. If you have any advice, please let me know. And possibly give me a website I could get one at also. Thanks!!
