Despite the hit or miss reviews, this thing has been basically spot on when I would compare my theoretical wheel speed based on rpm and the reported gps speed at the time. It never seemed to wander and only over reported by ~2-300rpm at the absolute highest rpms.
Of course, it has settings for a whole range of 2-4 stroke engines with various cylinder amounts.
If the motor hadn't gone bang, I could record it at idle (14-1500 rpm) with my pixel 3's 1/8 speed slowmo and listen for the 3.125 pops of the exhaust just to be sure on the low end that it's accurate.
The motor is/was a higher end zeda 80 which has been worked over by zedamotorsports to help bring out another 1-2hp. Where most low end kits are making 2hp on a great day, this thing makes 3-4hp on its worst (2-2.5 if your on the factory pipe and factory carb tuning). I quickly had to replace the shitty rag joint for a CNC aluminum adapter that would clamp onto the hub after throwing on an mz65 expansion chamber. Then I had to replace the wheel when I accidentally clutch dumped rolling from a stop light (yay potholes) and spun the adapter breaking a few spokes/bending the fuck out of the wheel.
After throwing on a 21mm PHBG carb, wide bore intake and a CNC aluminum head it had some fairly impressive grunt for such a small motor. Zedamotorsports offers a lower end motor that is basically the same thing as the one I blew up for half the price that I'll be buying next paycheck if the bottom end is completely fried on my current one.
That's an inductive pickup tachometer. I use one similar working on engines that don't have tachs.
