Description

Are the valves in your 4-stroke motorized bicycle not opening and closing as they should? If their rockers are intact but the valves won’t open, replace their rocker pin with this 4-Stroke Valve Pin. Made for 49cc 4 stroke engine kits like the Flying Horse 5G 49cc and HuaSheng 142F motorized bicycle engine kits, this pin is what’s stopping your motor from running as it should.
This pin helps keep the rockers for the intake and exhaust valves on your 4-stroke in place. To install this part you’ll need to take off and remount the rockers for your valves, slipping the pin in its port underneath the rockers. Once you’re finished, start your motorized bike, pull the throttle, and you’re riding in no time!

Part #63 on the 4-Stroke Diagram

This pin is a part of the intake and exhaust valve assembly of the Flying Horse 5G 49cc 4-Stroke bicycle engine kits, as well as most HuaSheng 142F engine kits.
