I'm 99% sure I broke a reed after about 2 hours on my 5mm 760/809 HPE setup. There is some fiberglass fray and black stuff in the intake, along with running like poop. I had my b pipe flowing way too much water and I revved it out. It took a bit for the pipe to warm up but once it did I was FLYING. I think the reeds couldn't take it. Anyone have trouble with these? I'm going to pull them off in a bit and get pics.
