I own a 2006 KLX110 and was doing some mods in these threads like rejetting, opening the air box and exhaust. I did these and it seemed to be running rich so I read the threads again and it said to adjust the air / fuel 2 turns out. Well I took off the carb and looked all around to find the screw and could not find it. Finally I looked at what looked like a cap that turned out to be the adjustment. I had to tap in a small socket to get it to turn. My question is are all KLX110 carbs like this ? Is there a special tool for this ? Is there a reason Kawasaki does this? I have looked at several other carbs (Mikuni) and they all have normal adjustment screws.
