I have a 09 DRZ400s and I'm doing the 3"x3" box mod, K&N filter and a aftermarket off road exhaust. I think it needs the stage 2 dyno jet kit but the only stage 2 kits say for the 00-10 drz400sm. I can find the stage 1 kit but the stage 2 says its for the modded box filter and exhaust.
Do you think the stage 2 kit would work on the drz400s even know its for the drz400sm? The stage 2 kit comes with the stage 1 kit and there the same for both bikes.
