A lot of the sensors can be tested with an voltmeter while on the bike. MAP and TPS usually have 3 wires each. One wire will be ground, the other power (5 volts) and the other signal voltage, which is usually low at idle increasing as you open throttle. I have checked them on other vehicles and outboards by inserting a paper clip into the connector on the signal and ground wires, then hooking up a voltmeter to read the voltage as you open/close throttle. A smooth transition from 1 to 5 volts and back should take place. Similar for MAP sensor but you would use a vacuum pump to test or the engine itself.
Here is one of many videos on how to test these sensors. how to test a tps sensor with a multimeter - Google Suche
