I have an '07 DRZ SM With Yoshi and 3x3 airbox. It was sold to me this way. I rejetted from a 155 to 170 and am I ever stoked! I recommend this jetting. I am not noticing any flat spots and shes really throaty now. I went as wide as possible in the bake tires and threw on Avons and shes got the super grip now. I need to look at my tire specs but I was wondering what PSI's you guys are running for street. I havent started playing with my PSI's yet. I am new here and new to Sumo so thanks for all your advice!
