Review on Dolphin1986 Performance Carburetor Bicycle Motorized by Mike Starling

Some adjustments may be required for tuning. The one I received didn't work very well, I contacted customer service and they were able to fix the situation fairly quickly. Excellent customer service. Good product. Be sure to google the setup instructions as there are no instructions included in the box. If you have any problems, please contact customer service, they will send you great photos with details.
