Easy to install but you have to be a little creative where to install on a DS450, We buble wrapped in and stuck it where the tool kit was beside the air box. Will buy another one.
Great to use on any 2-Stroke or 4-Stroke engine. Electric clock keeps time only while engine is running. It starts counting when it feels electrical pulse through spark plug wire and shuts itself off when the pulses stop. Helps monitor service intervals. DR.D Hour Meter starts working after 6 mins, and every 6 mins. after that.
