I recently went from 44 to 38 tooth sprocket. An my speeds an rpms have changed alot. Went from 26-29 mph cruising speeds and 4500-6500 rpms. To about 28-34 mph cruising speeds with much lower rpms. My issue is even when I start a slight increase in incline my rpms drop and speeds fall to a slow 25- but down hills well if it's a good long down hill I can manage 40 mph. I'm looking for ways to upgrade an add some torque an power to the little huasheng engine I have. I've already done the exhaust. And it helped some. Not so sure about carb filter upgrades or others ... anyone have any ideas ???
