Thats not a motor cog
That is the front chainring for a 1 piece BMX style pedal crankarm.
The hole will be much smaller than the one typically drilled for motor wheel cogs. If you can machine it out and accurately drill the holes, you can have any size you want from 20-50 tooth. What a pain though.
It would be easier to get a front shift kit chainwheel with the 5 holes, and drill 8 new holes for the 9hole grubee wheel hardware.
