Re: Common China Girl Carb Sizes

Now I understand why everyone says they like their Speed carb. Seems pretty big compared to an NT.

Re: Common China Girl Carb Sizes

my NT carb works just fine. Had it 3 years now. I weigh 280 (used to weigh 315, dropped a few lbs), I ride a beach cruiser with a modded pocketbike pipe, and I cruise at 29. air/fuel mix is right on, too. Had this engine a year, and expect it to last at least another year. Its a 68.5cc rice burner from BGF.
