Belt drive for 2cycle motor kits

[5-7HEAVEN]

What r u runnin .butre?
if I'm allowed to ask
I was wondering because I see those e200 razor scooters with belt drives. Obviously that setup may not work for the motors though.... Maybe something similar. I would prolly make a hole in the side of the cover to clear the width of the cog. My big QUESTION is would gearing ratios be the same. Because I see those one bikes with the big ol ring on the back wheel for a belt and I don't want that.

You have the power to change your gear ratios.

If your bike has a 10-tooth engine sprocket and 40-tooth rear sprocket,
use a 1" engine pulley and 4" rear pulley.
or a 1.5" engine pulley and 6" rear pulley
or a 2" engine pulley and 8" rear pulley.

Do not mix and match, if you want to keep the same gear ratio.

Mix and match to raise or lower gearing.

Yet nobody is doing it... Damn chains and sprockets being so practical and easy and already available!
