We bought a coolster 125cc four wheeler. It stated that it goes 43 miles per hour and it only goes 23. When we ordered over the phone the guy said that all we had to put together is the tires and put gas. No! We had the front rake, back rake, handle bars, steering, tires, battery, gas, all the stickers, back reflector. We contacted customer service and they still have not got back to us regarding the speed. This also has a hard time starting. We had to adjust the choke and it still doesn't stay running. This is just a pile of junk! Don't waste your money.
Hello, I Apologize for the inconvenience. In regards to the speed it sounds like you have not adjusted the speed governor. If the speed governor screw is not adjusted your unit will only go so fast. Please call in and speak to our tech dept so we can walk you through on how to adjust that.
