I got my Hyper back from the mechanic yesterday and it still feels rough and surgy at low speeds and RPMs. It also stalls off idle when cold, though mechanic says it just needs to relearn idle after ecu swap. Anyone up for taking it for a spin and letting me know what you think? I just want to make sure I'm not crazy and that it really does feel off. It runs great at full throttle, but just feels wrong to me at low RPMs and low speeds. I feel like I am using the clutch far too much at low speed and it sounds a bit lopey. Your welcome to take a spin on my Z125 as well if you want to give it a go. You can come out to my place or I don't mind riding to you if your fairly close. My wife has a brisket going in the smoker that I'd be happy to share if you come out my way.
