YS FZ63S FZ80S Questions
Hello,
I'm hoping someone here may know the answer regarding YS engines.
I currently have a YS FZ63S that started acting up. Inconsistent speed at full throttle, then when you throttle back it locks and stops. Has a slight clanking sound as well. I have reached out to CKAero for a service request, but they have not responded yet.
My alternate approach is to look at the new FX80S as it appears to be a drop in replacement (measurements look very similar).
My questions are as follows: I currently use a Hatori #643 header and #640 muffler. Does anyone know if this header will attach to the new FZ80S, and wheter the muffler is sufficient for the new FZ80S?
Thanks,
Andrew
