If they are measuring from the side the exhaust is probably what needs attention.

First step is to point the outlet away from the meter like a Max. You can use the add-on bend and silencer from a KF3 engine. For extra silencing an ADAC unit between the main exhaust and the end cap is cheap and effective.

The sound drops off at the square of the distance so adjust your line a bit to keep away from the meter without being too obvious.

Keep your revs down. The dBA scale that is normally used is weighted so that higher frequencies show a greater reading on the meter. As you are not racing you will probably find that you can take ten teeth off the rear sprocket and do similar lap times.
