MOPED ARMY

I’ve had an 80’ SSXL 25mph model for awhile that I’ve thrown a tric-matic 70cc kit, a polini performance pipe, and moved a 16sha over to it! Still really dragging on the acceleration. I’m in NYC and rarely face any serious hills. Just need oomph off the line. About to rebuild the bottom end, so wondering about gearing. It’s stock 10x36 now. Should I go big like 46T on the rear? 11 on the front? A mix? Need some takes. Thanks doggies!
