The first thing I would check is the cam position sensor, if the sensor itself looks like it is leaking, it is likely your issue. You can test it by starting the bike and heating the sensor with a heat gun, if the bike shuts down, let the sensor cool and it will re start. this is a common problem on EVO bikes.

 

 

 

The cam position sensor is in the cone at the bottom of your motor. there should be 2 screws or 2 pop rivets you will need to remove to access it.

 

What exactly did your $700 pay for? Sounds like you are saying he lined the fuel tank? What did the mechanic do?

 

Yes, you'd use the volt meter setting. The volt drop is a function of testing the circuit under load and voltage loss is a function of high resistance in the circuit. In many occasions you can test a circuit for an issue with an ohm meter and it'd show no resistance but keep in mind, there's little to no load placed on that circuit during that type of test. That's why a volt drop test tends to be more revealing. It tests the circuit under load and the high resistance causes a loss of voltage (and current) from one end of the circuit to the other end. That resistance under load also creates heat which then creates more resistance until ultimately, the circuit fails.
