Need Help I think my bike shit the bed, or did I?

[SAKE]

So Ive had my RC 390 four roughly 5 months and I cased a pothole roughly a month ago, bought new rims and tires, as well as new abs disks and replaced the rear stuff, everything was great, few weeks later replaced the front and now my bike has a plethora of problems suddenly, speedometer reads 0, bike pops like crazy, stalls when I pull in the clutch while moving, abs light and mtc light won’t turn off, had a yellow triangle but when I replaced the front wheel it went away but I gained all the new problems. Replaced with all OEM parts and the only lead I have is my dealership telling me my bike needs some proprietary checkup that they wanna charge an arm for. I’m I missing something simple? Or do I need this checkup from them.

definitely sounds electrical.the first thing I would do is double check all the connectors to see if any thing came loose. make sure tire clipped in all the way.
