I would check the kill switch or on/off switch as those work by grounding out the ignition system so there is no spark. After that the coil or magneto might be the issue.

Most backfires are caused by improper mixture settings on the carburetor.

If the shocks are worn out, get off the machine and lift up on the back rack. This takes up the slop between the shifter box and the transmission, and usually allows me to shift. I also had an issue with the thin steel plate behind the shifter box. Got a crack in the top , so it was flexing, creating more slop. Welded it shut, good as new.

Sorry I know nothing about the model but just wanted to mention, by 2013 you can expect passive immobilisers and everything carrying a code number and the various black boxes talking to each other and if they don't recognise each other by the code numbers embedded in them they simply won't work and fitting a computer with a different code could have put everything else in a really bad mood.

I think you need to research things a lot more deeply before you lay hands on either of them again.

It acts like you have burnt spots on the starter shaft that touches the brushes ( voltage) to start. When you rock the vehicle in gear the starter shaft moves and it is placed in a position where the brushes can make a clean contact. Then when you turn the key, the starter will engage and the vehicle will start. My recommendation would be to change out the starter.

Usually, there is a hole plug near the bottom of the casing. BUT first drive it around a lot cause gear oil is heavy and it won't come out very fast if it is cold.

Even though the overflow is full, the radiator could be empty. You need to remove the radiator cap and make sure it is full to the top. If you find the fluid level is low in the radiator, that would indicate there is a leak in the hose between the radiator and the overflow tank.
