If your 4-stroke motorized bicycle engine is misfiring or chugging when you ride, this 49cc Timing Gear will have your 4 stroke engine running right again.
The Timing Gear sits inside of the engine case and helps your crank system draw as much fuel as possible into your cylinder for combustion at the correct time. When it’s not carefully set your motor can experience incorrect timing, which can halt a motorized bike in its tracks. This gear is critical to your gas motor’s operation.
Compatible with a host of 4-stroke’s like Flying Horse 5G and Huasheng 142F 49cc 4-stroke motorized bicycle engine kits, make sure you have this gear handy when it comes time for those crucial repairs.
