I have a 70cc Treats Reed Kit + 4 Pedal setup, and after like 7-8 years of blasting my original 0.30mm reeds started to bend backwards. I flipped them around and kept blasting for another year. But I finally got a set of these to replace the worn out original 0.30mm reeds. I also wanted to try the thicker 0.35mm version. Holy shit, this was the missing key! High RPM top end boost added to my setup without changing jetting. Doesn’t feel like I’m hitting a wall at 48-50mph anymore, it now just keeps reving and sounds mean! Probably in the 52-54mph range.
