Hi Rob,
Sorry to learn you are getting issues with instrument cluster.
Start with the obvious i.e. the wire harness connection to the instrument cluster, check its secure, check there is no corrosion on it, if corroded use a spray can contact cleaner. I will not recommend a contact cleaner as there 100’s in the marketplace.
If the issue persists, I am sorry to inform you that it is more than likely the PCB i.e. the instrument cluster Printed Circuit board. A new PCB will be required, these can be repaired especially if its just a dry or cracked soldered joint, but you really do need some experience in these repairs with special tools and bespoke soldering irons otherwise one can destroy the PCB.
You can leave the bike in a garage or outside, in cold weather the inside of the instrument cluster filles with moisture, not ideal for electrical items of course. But until CFMOTO invest more into quality electricals with rubber humidifier sealing this is currently unpreventable.
