I just checked the reeds in my '02 Zx 440 and the center petal was just starting to slightly fray near the tip. This was present in the same location on both cylinders. The sled has 2100 miles. Should I replace the reeds? All the other petals looked fine. Finally, how do you know which style of reeds you have? Mine have screws and an adjustable plate. I believe the V-Force 3's did away with this.
