As an auto mechanic, he mainly needs advice on scooter/motorcycle specific issues...plastic removal etc...
Valve adjustments are unique on the Reflex. Remove crank view port cap. Find top dead centre mark. Remove cam port cap on other side of engine. Make sure that cam is in the right spot with a flat spot on top. If flat spot is on bottom, rotate crank one more turn until it's on top. Instead, i put my finger on the plug hole and feel for compression. When top dead centre mark shows up, you're ready. On the side of valve cover are external valve adjustment levers. Loosen one at a time and finger rotate until valve rocker starts to press onto valve. Back off one notch on lever dial and tighten. That one valve is set. Now do this to the other one. Do this with a cold engine.
Most important...give him directions to your favourite restaurant after it's all done!
