Question: Does the Tomos A55 engine have 2 pulses/rev. I got a Tiny Tach for Christmas and installed it. My rpms are maxing over 9999 rpms at top speed. The Tiny Tach Rep. replied:
The 2R model Tiny Tach is made for 2 strokes or 4 strokes that have one
pulse/rev , but some Mopeds will run RPMs above 10,000 and the tach will
reset and lock-up sometimes.
Some engines will accually have 2 pulses/rev on a single cylinder engine.
