my 08se does not have but 1 place on the needle where the clip can go. WTH
ninja did you ever take yours to the shop?im having problems getting my jetting right. idle seems to be OK. i think it might be on he rich side. im not having any problems on the wot. but in mid range its not running right..i think it would be called 'hesitating'. it acts like its lean to me but when i move the clip to richen it gets worse. same as if i leaned it..
i dont know what else to do besides having a shop shop do it and spending $$$$.

I happen to have the pics from the OP.. though I might be missing a couple at the end regarding the plug blocking access to the fuel screwDetroiter said:Yeah can OP or someone eles repost those pictures?
Duane said:Step 1: Drain the carb of gas.
Step 2: Unplug the TPS and carb switches to spin the carb. Unplugging is optional. You may have enough room to rotate carb without removing the plugs.
Step 3: Loosen clamps that hold the carb. One on the intake side (not shown) and one on the leaving side of the carb.
Step 4: Spin carb to access the jets by removing the 17mm nut at the bottom of the carb bowl.
Step 5: Replace jets as required. In these pics I removed the bottom of the carb to get better pics. YOU DON'T NEED TO DO THIS!
Step 6: Getting to the needle and clip. Remove the plate on top of the carb.
Under the plate you'll find an allen head screw that needs to be removed to get to the needle and clip.
Remove allen head bolt to remove the needle and clip.
Reach inside the back of the carb to "lift" the needle out.
Needle and clip.
WARNING: DO NOT MOVE THE TPS SWITCH WHILE DOING THIS!
That's my basic "jetting for dummies" tutorial. Make sure everything is clean before doing any of this because dirt is your worst enemy. After you're done make sure everything is put back in place and all switches are plugged in.
EDIT: This is what you'll see on the 06-07 YFZ's when it comes to the fuel screw access. Thanks to Fever2ride for providing the pics.
Yamaha blocked off the access with a plug and you can either pop the plug out by screwing in a sheetmetal screw or take the bowl off and punch it out from the inside.
