Trail Tech 72-A00
$28.78 - Amazon
I installed this on my 2012 Kymco in 2013.
I used 2 sided Red 3M tape. (No drilling in the scooter)
Fished the wires without removing any panels - except for the battery cover.
I check it every now and then after a ride - to see what my max RPM's were. or, while riding to see what I'm turning while on a country road cruise. It also records engine hours.
After 6 years it is still working fine.
Removed the seat bucket & wrapped as close to the spark plug cap as possible, then enclosed it loosely.
