There could be several reasons why your Interceptor 650 is experiencing a missing problem. Here are a few steps you can take to troubleshoot and solve the issue:

1. Check the fuel system: Make sure that the fuel tank is not empty and that there are no clogs or leaks in the fuel lines. You can also try using a fuel system cleaner to clear any blockages in the fuel system.

2. Check the air filter: A dirty or clogged air filter can restrict airflow to the engine, which can cause a missing problem. Check the air filter and replace it if necessary.

3. Check the spark plugs: Worn or fouled spark plugs can cause misfires and missing problems. Check the spark plugs and replace them if they are worn or dirty.

4. Check the ignition system: The ignition system includes the coils, wires, and distributor. Check these components for wear or damage and replace them if necessary.

5. Check the ECU: If none of the above steps solve the missing problem, the issue could be with the Electronic Control Unit (ECU). Take your bike to a qualified mechanic who can diagnose and repair any issues with the ECU.

It's important to address any missing problems promptly to avoid further damage to your bike's engine. If you are not comfortable performing any of these steps yourself, it's best to take your bike to a qualified mechanic who can diagnose and repair the issue.
