APS...
That proves my point.... Lets say the LEO is suspicious of the bikes tach reading. The bike just doesnt sound like 2800 RPM.
The problem is he cannot definitively say exactly what RPM the motor was spinning at the time of the test. He can only state that it was his opinion the motor wasnt spinning at the proper RPM. This invalidates the test, and wastes the time of the LEO and the courts should the LEO decide to write the ticket anyway!
Noise tests do not need to be made into a big production...... or require gyrations from the LEO's...
You need a calibrated Inductive Tachometer, a calibrated dB meter, and a tape measure!
1. Attach tach to spark plug wire, adjust tach for appropriate number of cylinders. (Note: this can be any spark plug wire. It doesnt have to be #1 cylinder) Spark plug wires are easily accessable on most V-Twin motorcycles.
2. Measure appropriate distance & angle off motorcycle. Place dB meter at appropriate spot.
3. Take a reading of the ambient noise level as noted by dB meter. This may be important for court.
4. Rev engine to 2800 as indicated by calibrated tachometer
5. Note dB meter reading and issue the pass/fail.
It doesnt have to be that hard or expensive.... I swear the politicians could screw up replacing a lightbulb!
Requiring morotcycles to have a tach or completely stock exhaust is just assinine!!
