Need help with diagnostics. The yellow k on panel flashes the engine idles now at 3500 rpms and will not excellorate past 4500 rpms. Scooter was running good when this started. I live in Kentucky USA there is no one here to help.
Last time I had something like this it came down to an air leak. Grab a spray can of WD40 or similar and spray it around the intake/airfilter/manifolds, see if the engine note changes. But it's a Jetforce, they're a pig, like most injected scooters. Give me a carb model anyday.
K is supercharger fault I think. Check the connections on the sensors, probably a manifold pressure sensor type thing that's gone.
