Just got a Pro Circuit Ti 4 Slip on for my 2007 YZ. I run twin air filters with No Toil filter oil. Should i buy the JD Jet kit?? Or what do i need to change to get this to run right? I would rather just change a few jets since i have a bunch laying around but i am not sure what i need to do. Everything in the carb is stock minus the quickshot and fuel screw. I ride 0 -500 Feet Desert in So Cal. Low Humidity 70 - 90 Degrees. Thanks!
