What should I run for a mainly street setup with 12" wheels and 120/70/12 tires?

I already have 13,14,15 for the front and only a 36 for the rear. Should I get a 33? and/or a 16 front as well?

You're the king, you should be telling us! JK This is some great info guys, one of the mods should sticky it. I'm about to start a motor build, and have a big industrial park lot that we race each other in. Once I'm done, I wanna GPS my bike and see what it'll do.



Current setup



Stock Jialing 124

3.0 X 10 front

3.5 X 10 rear

16 / 41 gearing



Bike pulls well in all gears, but runs out of steam on top. I'm about to cure that.
