Review on NICECNC Orange Air/Fuel Mixture Screw Adjuster for Keihin FCR Carb, Fits Honda Yamaha Kawasaki Suzuki CRF YZF WR KXF KLX RMZ Motorcycles by Stanley Redline

The best motorcycle part I have ever bought. Perfect fit for my '08 Yzf250, didn't even have to remove the carb. Instead of having an old-style sweetspot that was difficult to set up and had to keep guessing where it was, the numbers and easy rotation allow me to get it right every time I ride. Due to the extreme temperature swings in the state of Georgia, I always needed a tiny screwdriver and guesswork. Now I can get the most out of my bike. Also drove 2 hours in rough rock gardens today and it never budges. Buy, it's worth it!
