Congratts on the new to you 06 , stock form I agree that it's a dog -- Being in Callyforinication--- from what I have read here-- you might want to keep the ais on for show(4 the yogi's) but have it disconnected( plugged inside the tubes ) to get rid of the decal-popping - so that leaves you with needing to get a yz needle/ cut or buy a throttle stop screw and a 48 pilot jet! to start with ($40 ais kit, has what you need). The best mod on the 06 is an after market slip-on pipe( I recommend DR.D
s.steel ) or a used 03-05 yz's pipe! money wise? -- other mod's - grey wire and set the AP timing/O-ring mod, open up the air box and relocate the valve head hose that goes to the bottom of the air box, up under the seat or to the top of the air box and tee off the overflow carb vent lines and route them under the set or above the air box also( these are deep water crossing's mod's ).
