Did you check to see if the chokes on?

Its the oil injection tank. This is the oil that mixes with the gas. Without and oil/gas mixture your 2 stroke motor will be ruined due to lack of internal lubrication. Some people will disconnect them and premix the gas due to a fear of failure of the injection system.

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.

Sounds like you have a weak battery, test the voltage. If battery is fine then your starter relay is the culprit. Clean all terminals in battery and relay, corrosion on the connectors will cause this too

Bad battery connection perhaps. Remove leads, clean with a wire brush until shiny, then coat with Vaseline.

Then move onto the solenoid, check the voltage to operate and voltage at starter motor leads.

Finally, jump the battery direct to the starter.

Sounds like a short or one of main sensors is burned out.. Mite get a voltage meter and see if your getting
Power or not. Go to google Image and get the schematics of the main wiring
Systems and go threw it piece by piece.
Or you mite just have a main fuse blown. Get the schematics and check
Each system good luck.
